add dump/restore commands for ext4 fs maintenance
See https://www.system-rescue.org/manual/Overview/
You can use dump/restore for backing up an ext4 partition.
But there are absent:
[root@sysresccd ~]# which dump restore
which: no dump in (/usr/local/sbin:/usr/local/bin:/usr/bin:/sbin:/usr/bin/site_perl:/usr/bin/vendor_perl:/usr/bin/core_perl)
which: no restore in (/usr/local/sbin:/usr/local/bin:/usr/bin:/sbin:/usr/bin/site_perl:/usr/bin/vendor_perl:/usr/bin/core_perl)
At least, versions 6.1.6 and 6.1.8 affected, but in some old 5.x.x there are present.
