Karmic Koala UNR on AA1
Be warned! All is not good in the upgrade camp this early on… that said on an HP nc6400 no issues and on my Acer Aspire One UNR upgraded fine – apart from breaking my tmpfs mount /tmp area.
This is fixed by following the instructions here.
/tmp as tmpfs
As tmpfs no longer supports mounting of /var/tmp under Karmic Koala do these workarounds in /etc/fstab:
tmpfs /tmp tmpfs defaults,noatime,mode=1777 0 0
none /var/tmp aufs noatime,br:/tmp=rw:/var/tmp=ro 0 0
none /var/log aufs noatime,br:/tmp=rw:/var/log=ro 0 0
none /var/cache aufs noatime,br:/tmp=rw:/var/cache=ro 0 0
Reboot and things are back the way they where when you optimised your AA1 under UNR 9.04.
