#9689 Netinstall images are huge (~700MB)
Opened a year ago by augenauf. Modified a year ago

Netinstall images once were around 300 or 400 MB, not they are 700MB
Is there any way to minimize them again? (I realized that OpenSuse manage to ship their rolling-release distro on a netinstall of 150 MB)

Maybe we should look at their kickstarts and see how are they different.

I'm taking a look at the contents. My quick scan of the package sizes on boot.iso shows:

These are the installed sizes, not the compressed RPMs. The first thing I notice quickly is that we probably don't need both glibc-all-langpacks and glibc-langpack-en. The former is a superset of the latter.

The firmware packages might be a good place to look, given how we install firmware in the lorax template - basically we install *-firmware, with a list of specific exceptions. If any of those -firmware packages up near the top of the list isn't actually needed in the installer environment, we could add it to the exceptions and save a chunk of space.

(I realized that OpenSuse manage to ship their rolling-release distro on a netinstall of 150 MB)

openSUSE's netinstall images are split into two: a base image to boot up YaST, and an image to run YaST itself. The latter is not embedded in the netinstall ISO. This allows the base netinstall ISO to be quite small, since most of the environment does not need to be included on the ISO itself, but fetched and loaded into RAM from the network directly.

This is also similar to how it works for Mageia's netinstall media, too...

that's how anaconda used to work long ago, but we combined the stages.

sadly, netronome-firmware, iwl7260-firmware and liquidio-firmware are all network firmwares, so we probably can't kick them out. (netronome and liquidio are for fairly specialized enterprise-level NICs). netronome seems to be extremely inefficiently laid out - it's 1.7M as an RPM but 140M(!) expanded. It contains a ton of 5M-sized files which I guess are extremely compressible, perhaps they're mostly empty space but have to be exactly that size for some reason. I'm not sure how much space those actually account for in the size of the netinst ISO images, I'm not sure if they get efficiently compressed in that context or not.

I wonder why we can't store them compressed on disk? Doesn't the kernel support loading zstd compressed firmware files?

I think we could strip *_video.so from /usr/lib64/dri (in mesa-dri-drivers) as I think those are only used for accelerated video playback, which we don't need in the installer. Unless anything would get sad that they aren't there. That's ~25M (uncompressed). I'm not sure if we could possibly lose one out of swrast_dri and kms_swrast_dri...

I am building foreman-discovery-image (server hardware inventory LiveCD based on CentOS7 for PXE-booting) and I experienced huge size growth from 145MB (CentOS 7.0) to whooping 400MB (CentOS 7.8).

One trick I want to share is use of rdfind tool, duplicite files finder tool. When I executed it on /usr and /lib it found about 20MB on my system (I don't have X Windows), mostly timezone info and some firmware files. But when I added this to my kickstart, it actually saved almost double the size on the compressed squashfs for some reason. I recommend to take a look into this.

I've done some digging into this. The first quick fix is possibly change the squashfs compression algorithm. When I was doing some tests, I wasn't sure which compression was used for the build, so I used xz (squashfs -comp xz) and the rootfs.img went from 585M to 566M. Not a huge leap, but enough to keep it under the 700M limit.
But, that is only a short term fix.

The big problem is (as is stated above) firmware. I exploded all the rootfs.img from F17 to the latest F33 build. The most interesting points are from F28 to F33. That's just three years. The firmware has grown from 282m to 573m. All the rest of the programs in the rootfs, haven't gotten any bigger.

F28 Adjusted: 1268m  (1552m overall - 284m firmware)
F29 Adjusted: 1268m  (1576m overall - 308m firmware)
F30 Adjusted: 1337m  (1776m overall - 439m firmware)
F31 Adjusted: 1329m  (1809m overall - 480m firmware)
F32 Adjusted: 1268m  (1793m overall - 525m firmware)
F33 Adjusted: 1278m  (1851m overall - 573m firmware)

Oh, one of the other things I did was took out the entire netronome firmware (140m) to see how much is saved compressed. As I said above, I used the xz compression and it saved 12m.

Looked at two other things.

Using rdfind, I had it hard link all the duplicates. This reduced the uncompressed size by 50M, but after it was compressed, didn't change anything.

From the F33 image, I deleted entire firmware directory. I know it's not practical, but I wanted to see what we save if we did that.

Uncompressed:
Before: 1851M
After: 1278M
Total Change: 573M

Compressed:
Before: 566M
After: 357M
Total Change: 209M

Using rdfind, I had it hard link all the duplicates. This reduced the uncompressed size by 50M, but after it was compressed, didn't change anything.

That's exactly the opposite from what I saw, weird. Most of the files were from /lib/firmware in my case, have you also deduped this one? I have doublechecked any my size went from 342M to 338M, not huge but something. I had to sneak in some other change when I said "it was double the size of uncompressed". That was not true, uncompressed savings are about 20MB, compressed it's 5MB.

The tool leaves quite big log file behind, make sure to redirect this to /dev/null:

rdfind -makehardlinks true -outputname /dev/null /usr /opt /lib

I was testing this with the default (xz) compression for the record. Maybe 1M block size makes this irrelevant if files are close to each other on the filesystem.

We've had issues in the past with anaconda pulling in firmwares for 3D printers. The liquidio and netronome can probably be excluded. Servers that have these interfaces usually have "management NICs" that are used for actually installing and ssh and the like because the NICs at early boot are basically useless without the firmware or have minimal viable functionality so I feel they can be excluded without issues.

well I'm way into the weeds on this one. Currently looking through https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/WHENCE and adding lines to strip all firmware files that aren't to do with networking, graphics, serial devices and so on - anything not actually needed for an install (like audio, TV cards and stuff). There's a lot of extremely old or extremely niche networking firmwares in there, but leaving those alone for now.

Also, this is fun: I believe gtk2 is included because lxpolkit requires it. Why are we dragging in lxpolkit? Because blivet-gui-runtime needs a provider of PolicyKit-authentication-agent. I think adding an explicit install of polkit-gnome should help, will test.

I'm working on a branch with several changes to try and help as separate commits, will try to submit a PR later tonight or tomorrow.

Here is a spectacularly huge rpm dep visualization of something that approximates the installer environment before stripping. I produced it by just installing all the packages logged in the lorax logs (for today's Branched) to a mock chroot. I had to install rpmorphan to produce the dotfile, so rpmorphan itself and its deps are included; can't do anything about that. Also things that are required in any mock chroot are there, some of them may not necessarily be in the installer env. But it's something.

I don't see an awful lot of useful info besides the gnome-firmware and gtk2 things I already saw, but I might be missing something. It's a big picture. :D

Dropping gnome-firmware and specifying polkit-gnome instead of lxpolkit saves ~8M. My current test image is 741343232 bytes. Still working...

polkit seems to be the only thing dragging in mozjs78, which is ~28MB. We only have polkit to make blivet-gui happy but it shouldn't actually need it in the installer env. We could try stripping the library file and see if anything breaks, but we could also look at somehow splitting the package more/differently so anaconda can get blivet-gui without the polkit dep?

My first attempt at chopping some more firmware files from linux-firmware gets us down to 734003200 bytes. Which is exactly the size limit. Job done! :D

I'll do a quick boot/install check on it tomorrow and send a PR.

I did a hacky test of the polkit thing - I booted the installer, stopped polkit.service, deleted /usr/lib/polkit-1/polkitd , masked polkit.service , and ran through advanced custom partitioning (i.e. blivet-gui). It worked fine. So yeah, that seems attackable.

I went through runtime-cleanup.pl and did a big...cleanup. A test image built with those changes is 727711744 bytes. Will run it through openQA tomorrow and see how it does, then send a PR.

So current status here: my initial PR was merged for Rawhide and we've had a Rawhide compose since then; nothing obvious went wrong. https://github.com/weldr/lorax/pull/1073 is the same PR for F33. I also have a couple of further proposals to reduce size more:

both are proposed for Rawhide for now, but can easily be proposed for F33 too. I have one more firmware change proposal queued up which would need to go on top of the Mellanox one (dropping dpaa2 firmware on non-aarch64 arches).

@tdawson

I wasn't sure which compression was used for the build, so I used xz (squashfs -comp xz) and the rootfs.img went from 585M to 566M.

Compose uses -comp xz. But did you skip the nested ext4 file system that's inside the squashfs? In my testing that accounts for ~38M reduction, when eliminating the nested ext4. There is a Fedora 34 (also Fedora 32 but rejected) proposal to make it possible for koji and pungi to leverage existing support in lorax and dracut for plain squashfs images (no nested ext4).

Using rdfind, I had it hard link all the duplicates. This reduced the uncompressed size by 50M, but after it was compressed, didn't change anything.

mksquashfs does file level duplicate checking by default, and uses hardlinks (applies to plain squashfs images, not ones with a nested ext4 image).

So https://github.com/weldr/lorax/pull/1073 is merged now. I sent F33 versions of two further PRs:

I would say we should merge at least one of those two, then do an F33 lorax build+update and mark it as fixing the bugs...

So now we have a new lorax build that we hope ought to get things under 700MB.

But did you skip the nested ext4 file system that's inside the squashfs? In my testing that accounts for ~38M reduction, when eliminating the nested ext4.

How do I do that? Is this possible with livecd-creator as well?

It's --squashfs-only in lorax, more in this anaconda PR. And this koji issue. livemedia-creator does, I'm not sure about livecd-creator.

This is supported in livecd-creator with --flat-squashfs. See: https://github.com/livecd-tools/livecd-tools/commit/9d7648470b1d15e1af9fa080851f5a75a26d9436

A new lorax build with several of my changes has now gone stable which will help cut things down to under 700M, hopefully. For Rawhide, we have one more change in lorax, plus there are a couple of compression-related changes proposed or implemented, and today's x86_64 Everything netinst is 706740224 bytes. Which is...better. I dunno how small we have to get to close the bug. :)

I've used --flat-squashfs with CentOS7 live image I create but dracut is unable to mount it with error /dev/mapper/live-rw does not exist. My flags are rootflags=loop root=live:/fdi.iso rootfstype=auto ro rd.live.image acpi=force rd.luks=0 rd.md=0 rd.dm=0 rd.lvm=0 rd.bootif=0 rd.neednet=0. Is there something I need to add on the kernel command line? I see rd.live.overlay.overlayfs mentioned in the patch, I am unsure what to remove tho.

sorry, I really don't understand the question?

I brought up the nested ext4 and plain squashfs image type, which affect image size but are otherwise off topic. The plain squashfs image type needs different boot parameters to setup the overlay: nested ext4 images use device-mapper based overlay and the plain squashfs image use overlayfs - hence @lzap asking about rd.live.overlay.overlayfs. My suggestion is to bring it up on the related devel@ thread I mentioned.

Yeah sorry that is exactly my question. I have successfully built CentOS7-based image via livecd-creator however it does not boot. What are the kernel command line options? Are those features even supported in CentOS7 kernels? I will ask there thanks.
