[libvirt] RFC: Post-install behavior of libvirt(-client)

Hello everyone, I have a small bug #786770 [1] assigned and I discussed this with few people from our team but I'm still not sure what should be the proper fix for this bug. To sumarize the bug, the problem described and discussed there [1] is that when there's a fresh installation of RHEL system with libvirt-client, there are some error messages displayed. These messages are generated by the part of %post client script where we are running this: if [ $1 -ge 1 ]; then level=$(/sbin/runlevel | /bin/cut -d ' ' -f 2) if /sbin/chkconfig --levels $level libvirt-guests; then # this doesn't do anything but allowing for libvirt-guests to be # stopped on the first shutdown /sbin/service libvirt-guests start > /dev/null 2>&1 || true fi fi The messages are generated because "/sbin/runlevel" returns "unknown" in chrooted installation environment. But there's more to that. While looking at this part of code, I wonder what we are trying to do here :) There are some problems, let me revise: - 1st parameter of this script is 1 for install and 2 for upgrade, thus "[ $1 -ge 1 ]" is always true - we are trying to get the current runlevel and then check if libvirt-guests is enabled in this runlevel. As mentioned before, the latter doesn't work because we are using command "/sbin/runlevel" there. There is another option, but unfortunately, running "/sbin/chkconfig libvirt-guests" fails as well. Both of these are trying to get current runlevel from "/var/run/utmp" which is empty in the chrooted env during installation. Thinking about this a little more, I see two more "unconsistencies" let's say: - we are starting libvirt-guests if it is enabled (rpm post script should not start services) - we don't check if libvirtd is running, so during shutdown we can get even more error messages that the script is not able to connect to libvirt etc. So I'm wondering if I can just remove the starting part (because if someone wants to use it after first install, he has to start libvirtd anyway and then should know to start libvirt-guests as well) or if I have to come up with some totally different solution how to do this. Maybe I'm missing something here or I don't understand it correctly, any correction is appreciated. Thanks in advance for all suggestions.
