I have var/run on tmpfs, and this is backedup and restored from the kernel initscript.

Just managed to play around with the netbook. udev 1024 428 596 42% /dev /dev/rootdev 4194304 1770968 2423336 43% / tmpfs 917504 65888 851616 8% /tmp tmpfs 917504 65888 851616 8% /var/tmp tmpfs 917504 65888 851616 8% /var/run tmpfs 917504 65888 851616 8% /var/log tmpfs 917504 65888 851616 8% /media tmpfs 917504 65888 851616 8% /home/tmp rc-svcdir 1024 72 952 8% /lib64/rc/init.d shm 1024788 804 1023984 1% /dev/shm Everything works fine when I unmount /var/run and chattr -i on /var/run on the root file system. The /var/run/Consolekit and /var/run/polkit-1 dirs already exist on /var/run on tmpfs. These are created before the real init is run. The problem, as far as I can tell was that some cruft was being created on the root file system below the mount points, which the chattr +i fixed. ie should have been created in tmpfs: var/run not rootdev: varrun. So if I unmount /var/run everything is fine. I didn't check to see if the directories are still created on rootdev:var/run instead of tmpfs:
This is fixed in git: http://git.overlays.gentoo.org/gitweb/?p=proj/portage.git;a=commit;h=ea30a50c3b0c32eed3169906a51d16b19cb5793f
This is fixed in 2.1.9.27.
(In reply to comment #5) Thanks. Works fine.
