Hi DongInn,
Upstart is a replacement for sys V init. It was developped for Ubuntu but was
used by other distros. Fedora 9 and rhel6 are using this (initscripts are still
compatible so upstart support is not mandatory), but since fedora 15, redhat
went for systemd.
Now, (except ubuntu) many distributions have moved to systemd.
http://en.wikipedia.org/wiki/Upstart
As for SuSE, I'll go for zypper then and make change if needed in the future.
Though, SuSE support is not my priority. I need to fix many many stuffs in
oscar so it works on OS other than rhel6.
My fixes and ports are aimed at:
- fixing ifconfig usage and parsing it which is broken with recent ifconfig
releases=> replace by parsing 'ip addr'
- fixing service management (so systemd works without needing to write a single
line of new code).
- fixing OS_Settings by adding most specific stuffs here instead of
hardconnding them. (dhcp config files, postgresql datadir and such).
Fedora-17 is an excellent platform to test this migration, almost everything is
broken (new ifconfig, new config file locations, system commands are in /usr
not in /, ...)
So far, I'm able to reach step 6, and add a MAC to a node.
Still need to fix enable install mode, setup network boot and most opkg
post-install scripts. (hopefully this will be fixed tonight).
Hopefully, after this big change, port to another OS should be far more easy.
Also, consistency should be more present among oscar files. For example, I'm
using OSCAR::Network instead of local functions when dealing with network
stuffs. (e.g. interface2ip is used in mkdhcpconf instead of local ifconfig
broken parsing).
With this move, many stuffs that were broken under debian will start working.
(no more redhat centric hardcoded config files (pgsql datadir, dhcp config
file, ...)
Last point: systemimager is broken for fedora-18+ (thus my testing on fc17).
(Can't build udev, need to move to systemd or find a way to build newer udev
from systemd source which is in theory possible, but not wide spread).
I need to work on systemimager to replace the build of the kernel and initrd by
a more modern technique that would use system installed materials (just like
the process to create the distro install boot disks). (though it's a little bit
out of topic here).
Best regards,
Olivier.

Hi Olivier,
(upstart not supported).
What do you mean by this? Does this mean that we can not setup a start up
program with “upstart” on a deb based system?
BTW, can someone tell me is SuSE server has zypper command (yum counterpart for
OpenSuSE)?
I have not setup SuSE myself but IU has a SuSE cluster (BigRed II) and it seems
to have it.
Regards,

Hi,
I'm still working on the migration to new SystemServices, SystemServicesDefs
and OS_Settings API so services management is transparent to underlying OS
technology (manual, sysvinit, systemd) (upstart not supported).
Aside that, I gave a look at OpenSuSE-12.3, and early steps for a future
support of this OS has been set up. Though, there is still work needed to
support the package management commands (zypper).

OpenSuSE)?
