Don't do it without approval of re@ (who might be too busy just now
anyway) It might blow the limit on the tight packed rescue floppy.
(& though desk workstations have CDs, lost of small boxes still
just have floppies for rescue) Best try to build a rescue floppy
yourself before adding bloat.
BTW I've never used pgrep thus superfluous to rescue. Others also
not really needed, merely nice. True rescue is just to fix FS at
which point you can mount other FS or CDROM or NFS etc for more
tools.
Before anyone else might discuss which tools might be nice, I'd
suggest build yourself a FIXIT floppy, & see what space is left, &
what you'd have to chuck out to make space for what you want to
add.
