Re: [Libguestfs] [PATCH] sysprep: handle distro specific sysv scripts
Hello,
(sorry for the late reply, I was not involved in libugestfs until
recently.)

Currently firstboot would only work on redhat-based images.
Handle redhat-based, suse-based and debian guests, error out in case
of an unknown distro.
Update firstboot.sh:
- make sure scripts exists and can be executed
- add LSB header to avoid insserv warnings later on
- run script only if called with "start"
Update functions, pass only required options.

This basically means that the firstboot script can be executed ahead of
anything else; thus doing something like
virt-builder debian-7 --firstboot-command "du -hcs /usr/share/doc"
can fail because of /usr not mounted yet. Likewise for other kind of
commands.
I understand that this functionality might be used to do simple stuff,
but still IMHO it would be better to have it run after all the other
facilities (at least the standard ones) are available, so I would
propose to change the written LSB header into:
# Required-Start: $all
# Should-Start: $null
# Required-Stop: $null
# Should-Stop: $null
(or just remove the two Should-* and leave Required-Stop blank)
What do you think?
(Firstboot scripts are not working in Debian anyway, see #1019388.)
