No it's not. Anything in your root directory should be considered off
limits, required for minimal functionality for repair. Either that, or
you use a bootable dongle for that purpose. All packages get installed
to /usr (or /usr/local depending on the system) so give that its own
partition. Snapshot before doing updates. If you get the system into
an unsortable mess, drop back to single user mode, unmount /usr, roll it
back to the snapshot, and bring the system back up.
