Description: dscreate was not creating its config file in /etc/tmpfiles.d/ like
setup-ds.pl used to do. The absence of this config file prevented
the server from being started afetr a reboot.

If using prefixed install, then tmpfiles directory won't be picked up by systemd-tmpfiles-setup service, since it looks only in these directories:

       /etc/tmpfiles.d/*.conf
       /run/tmpfiles.d/*.conf
       /usr/lib/tmpfiles.d/*.conf

       ~/.config/user-tmpfiles.d/*.conf
       $XDG_RUNTIME_DIR/user-tmpfiles.d/*.conf
       ~/.local/share/user-tmpfiles.d/*.conf
       ...
       /usr/share/user-tmpfiles.d/*.conf

as listed in https://www.freedesktop.org/software/systemd/man/tmpfiles.d.html

Hey, this isn't the fix. The point is that content on /run maybe destroyed at any time.

We should not be relying on lib389 to provide supporting content for ns-slapd.

The fix is that ns-slapd should only need a dse.ldif, and then it should make every other resource it requires. This is critical for newer systemd, tmpfs /run, and containers that don't always ship with state provided.

I would like this to be rolled back, and the fix should be in ns-slapd after dse.ldif is read, we should make all the directory paths we require, with the correct permissions.

Thanks,

mreynolds commented 5 years ago

Ahh okay. I'll work on this shortly...

@mreynolds Thanks, there is a longer justification on the mailing list. Really appreciate your help with this :)

Absolutely! Nice catch! I forgot about containers in this regard, just like we are not going to use upgrade scripts anymore - ns-slapd has to do it all. I'll get to it soon!

firstyear commented 5 years ago

Great! Maybe I should get you to do nothing but containers for a few months ;)
