Depends on the machine you have to restore :)

Then this mean you can't work on any other machine than your own. I don't
setup things this way :)

Where you told it to save.

I maintain, a backup of the *system* shoudl't require /var. libc.tags or
db/pkg is part of the system.

The system doesn't create these, they're part of the system (they're there
at install time).

So for you too it would be more consistent if db/pkg was with /usr/pkg :)
