Hi Mike,
Currently it is not support, at least not the same way you can do like
0.5.2. There are some problem on it once 0.6 is now using aufs.
The /var/log you see in 0.6 is an aufs filesystem, which is mounted
using two branches. At the bottom the read-only /var/log and at the top
a tmpfs /lib/init/rw/var/log. All changes goes to /lib/init/rw/var/log.
The problem is since there are running process are using files in
/var/log, so you cannot unmount or remount /var/log after sync operations.
I am exploring a way to have a new options that all writes will go to a
standalone tmpfs using mount --bind options, so that when setup /var/log
1. mount /var/log to elsewhere say, /ro/var/log
2. copy /ro/var/log to /lib/init/rw/var/log
3. mount --bind /lib/init/rw/var/log /var/log
4. then you can do sync from /var/log to /ro/var/log periodically.
5. Before reboot, sync /var/log to /ro/var/log.

Punky

Hi All
Any ideas about how I might be able to sync the aufs to flash with our a
reboot ?
