i have dark memories of updating a sunos machine many years ago.
the disk got kinda full and we were in "WTF do i do mode".
my blender broke down so i had to send brian out to get a new one
'cause we needed more cocktails.

we could only use static linked progs because the libraries weren't their yet.

many shell scripts were involved.  "rm" was dynamically linked, very
handy when you want to clean things up.

ed worked and shell script "rm" which did an "echo > $i" and a few
others got us thru the rum & fruit based twilight zone.

(yes - it's not the same but it frees stuff.)
