Hi all,

I once wanted to make /var/log not volatile, but then I realised that 
not preserving logs between reboots doesn't seem to bother any user, so 
I dropped the patches and marked the bug NOTABUG.
(https://bugzilla.yoctoproject.org/show_bug.cgi?id=3397)

So the key problem here is, are we going to preserve logs between reboots?

If so, we can make /var/log not volatile, in the same way Laurentiu did 
with /var/cache, and add the following lines to the 
read-only-rootfs-hook.sh script to make things work in case of a 
read-only filesystem.

mkdir -p /var/volatile/log
mount --bind /var/volatile/log /var/log

Best Regards,
Chen Qi
