well - why give you root-access to him?
it easy to hack your own system: just press <shift> when lilo starts and
type "linux init=/bin/bash rw" or somethig like this. or if you have a
dos-system on another partition, then you can do
"loadlin zimage init=/bin/bash rw". all of them give you a password-free
root-shell (anyway - it has it's quirks ...).
if you insist on the auto-password-reset, then try this:
awk -F: '{if($1=="root") print $1 ":saved-string-from-shadow:" $3
":" $4 ":" $5 ":" $6 ":" $7 ":" $8 ":" $9; else print}'
</etc/shadow >/etc/shadow.new && mv /etc/shadow.new /etc/shadow
(all on one line)
saved-string-from-shadow must be replaced with the strange kToB98CvTYOH6
(of course it's different for you) which is currently in your shadow.
note, that anyone with root-access can render this system to do exactly
the opposite of the thing you want ...
