Hi,

I was following the vinum setup instructions at
http://org.netbase.org/vinum-mirrored.html and as part
of it, I had to create a new /var in a vinum mirrored
volume. Once I created the fs, I copied over all the
contents of existing /var onto it via the command

cd /
mount /dev/vinum/var /mnt/var
tar -cf - -C /var . | tar -xpf - -C /mnt/var

However, while trying to remove the old /var, I figured
out I couldn't remove /var/empty (which was then renamed
as /var.old/empty. I realised it is because of schg
flags on the directory. The new /var doesn't have this
flag set either. I was able to delete and create it again.

So what other info could I have lost with this tar/un-tar 
process? Is there a list of 'must have' file permissions
somewhere that I can cross check against?

Any help is appreciated
