Hello again!
I noticed that if I backed up /export and then removed /export
completely it didn't restore to /export but to /usr/compat/linux/export.
I had to create /export to get it to restore there.
This got me wondering about the /usr/compat/linux structure.
I moved everything out of /usr/compat/linux and tried vbda.
I had to restore lib and etc in /usr/compat/linux to get it
running, but the rest don't seem to be needed! Which means that
I can now for example browse my real FreeBSD /usr. I am just now
running a complete backup of /usr to see what happens when I restore
some of the files in it. Should work fine as long as /usr exists.
I have no idea what this does to the linux support, it is probably
not so good if you use the linux support for other things than
omniback. I know nothing about linux, I just installed the linux
support to get the omniback client.
