The wonders of the UN*X shell! :)

No, don't.

(And if you want something to be run at regular intervals, then use
cron or anacron).

Well, it appears it *is* being handled automatically, there is only one
kernel on your system (at least in /boot). I would have expected it to
be two kernels there, the one you are currently running, and the one
before it as a backup, but that is not a big issue.

Is /boot on a separate partition, or a part of / ? You can find out with
"df /boot". If it is listed as "/" under "Mounted on", then it is a
part of /, otherwise it will be listed as "/boot".

I suspect it is indeed a part of /, and that / is beginning to fill up.
If it is a separate partition, then run "du -sh /boot/*" to see what is
filling it up. If it is a part of /, then it is time to do a little
spring house-cleaning :)
