+Run febootstrap-supermin-helper as an alternate user and/or group.
+C<user> and C<group> can be specified as either a name, which will
+be resolved using the system name service, or a uid/gid.  Use of these

+Use of these options is required if running febootstrap-supermin-helper
+as root with the effective uid/gid set to non-root.  Bash will reset
+the effective uid/gid to the real uid/gid when invoked.  As
+febootstrap-supermin-helper uses bash in parts, this will result in the
