fuidshift - uid/gid shifter
- UID/GID shifter
- This tool lets you remap a filesystem tree, switching it from one set of
UID/GID ranges to another.
- This is mostly useful when retrieving a wrongly shifted filesystem tree
from a backup or broken system and having to remap everything either to
the host UID/GID range (uid/gid 0 is root) or to an existing container's
range.
- A range is represented as
<u|b|g>:<first_container_id>:<first_host_id>:<size>.
Where "u" means shift uid, "g" means shift gid and
"b" means shift uid and gid.
