Testing rawhide on OLPC XO laptops. In /etc/sysconfig/readonly-root we set TEMPORARY_STATE=yes This means that various paths listed in /etc/rwtab get mounted as tmpfs, avoiding writes to the underlying disk in those paths. /etc/rwtab contains (by default) /var/run, which is now a symlink to /run, which is important for systemd. So what happens now is that systemd creates an important socket in /run very early on, then later on during boot, the rwtab system mounts a new tmpfs over /run, which causes systemd to be quite unhappy, as described in the thread at http://lists.freedesktop.org/archives/systemd-devel/2011-May/002253.html Not sure if this bug is in systemd or in initscripts - please reassign if I guessed wrong.
This needs to be fixed in whatever package provides rwtab. Which seems to be initscripts. Reassigning. (in fact, rwtab could use a number of fixes, like for example removing /media.
Created attachment 499210 [details] potential patch Does this work for you? It fixes the obviously wrong entries.
Bill, Works for me testing F15 based ovirt-node livecd. systemctl reports all the right info.
