>Description:
make installworld will fail if you do it as non-root user.

I think "make installworld" should warn user about running with non-root UID, and maybe ask for a "Press Y to continue", and should let me install the world correctly, without failing on "permission denied".

In the perfect case, such installation would create a script e.g.: perms.sh in $DESTDIR/, so that once booted, I could just do sh /perms.sh and have everything be fixed.
