Hi all,
here is a update on the work done on systemd for Factory :
(beware, email is long !)
- basic support for systemctl in chkconfig and insserv is done : it is
pending review by maintainer before integration
- support for --root in systemctl was merged upstream and will be used
by chkconfig/insserv patches above.
- a patch has been submitted to upstream systemd to parse insserv.conf :
this patch only handle the "system facility" part of insserv.conf and
automatically adds depencies specified in the file
- quick investigation on Yast2 to adapt runlevel editor for systemctl
support : we really need help from other people, as I don't have any
knowledge of Yast internal and it seems the yast dbus client part might
be missing some parts, needed for runlevel editor to talk with systemd.
- no work on /usr as separate partition : it is not a systemd issue in
itself but from other programs which might be using data from /usr
before /usr is available. The best solution would be to mount /usr from
initrd => help needed !!
- (open)SUSE is using unofficial LSB target named $ALL which is supposed
to put services requiring it at the end of the boot sequence (or at the
beginning of shutdown sequence); After discussing with upstream : on a
static boot system (sysvinit), it is easy to resolve such dependencies,
but it isn't on a dynamic system (systemd). There is a ugly hack to
handle that (creating a ALL.target file which is starting after
default.target is done) but it would be probably better to just fix the
4 initscripts which are still using $ALL ( amazon-late,
stoppreload, Susefirewall2_setup and vboxes). I'll open bug for them.
- X-Interactive support in systemd is not working properly : it will
only work before getty is started and is broken if you try to start a
service after boot. We need to transition packages which are still using
X-Interactive to systemd-ask-password (which takes care of the async
conversation). Only two packages need to be ported :
* apache2, when querying password for SSL certificate : apache allows
to start a script to handle the password request. We only need to
* openvpn : this one is a bit complex because we can either write a
daemon which would do the interface between systemd and openvpn
management interface or we can try to patch openvpn to have a similar
feature as apache and get this patch upstreamed. The latter has the
preference of systemd upstream.
For both packages, help is welcome.
For compability with sysvinit, support for <interactive>
from /etc/insserv.conf in systemd was not added, so we could
remove X-Interactive from openvpn/httpd sysvinit scripts but still have
the function when booting from /sbin/init, thanks to /etc/insserv.conf
list.
- /etc/init.d/kbd was not handled properly : this should be fixed in
Factory today or tomorrow, with systemd taking care of setting up
keyboard properly. However, we might need to
improve /etc/sysconfig/keyboard parsing in systemd. More tests are
needed (and of course, help is welcome).
As you can see, we still have some work to do, but we need everybody
help : either on the issues I mentioned (feel free to say "I want to
help on this" here) or to do more tests or even to start
creating .service files (but we still need to fix the issues listed
above).
Thanks everybody for your attention.
I would be great if we could get the ball moving and maybe get one of
the next Factory milestone be a "systemd" test release but to reach this
point, we need YOU !
