It's not a POSIX-compliant ps implementation.  Anyway, initramfs-tools
doesn't need it.

klibc-utils doesn't implemnt rm, only nuke.  busybox could install nuke
in the initramfs as a wrapper for rm.

initramfs-tools used to use switch_root if possible, but it didn't
support the -d (drop capabilities) option.  Later on we needed
validation of the init filename to support symlinks (e.g. /sbin/init ->
/lib/systemd/systemd), so I added and used the -n (dry run) option to
run-init.  busybox would need to support both of these.

Go for it.
