# 20220425 bkw: avoid conflicting with Slackware's restore. the old
# version of this script installed dump's restore in /sbin, and didn't
# mess with Slackware's /usr/sbin/restore... technically not a conflict,
# but a landmine anyway (it would be all too easy to type the wrong
# path to the restore command). rename it.
