One can then compile a list of thoose binaries. It will obviously
depend on your system/s.

booting:
grub, lilo, other boot loaders, init, sh
restoring, recovering, repair:
tar, dump, cpio, *fdisk, mkfs.*, fsck.*

A possible list could be:

/bin
attr, basename, cat, chgrp, chmod, chown, cp, cpio, cut, date, dd,
df, diff, du, echo, find, free, grep, groups, head, hexdump, kill,
less, ln, man, md5sum, mkdir, mv, ps, pwd, readlink, rm, rmdir, sed,
sh, sha1sum?, sleep, sort, stat, stty, sync, tail, tar, tee, time,
touch, tty, uname, uniq, wc, which, xargs

/sbin
badblocks, blkzone, blkid, blockdev, depmod, dump, e2*, findfs,
fdisk, fsck*, fstrim, fsync, halt, hdparm, hostname, init, insmod,
ldconfig, loadkmap, lsmod, makedevs, mdadm, mkfs.*, mkswap, modinfo,
modprobe, mkfifo, mknod, mount, poweroff, rdev, reboot, rmmod, swapon,
umount, xfs* (if you use xfs)

Add your boodloader.

Possible additions:
*acl, *attr, de/compression programs, network setup programs

Any more?
