Well, that's a little... scary. *frown*
Except that... I just deleted the rest of what I first wrote because
it hit me. Autoremove is what apt-get tells me to use to remove
packages..... that are no longer needed.... that are no longer
"dependencies". What it actually tells *me* is something like "apt
autoremove" (not "apt-get autoremove").
Aaaahhhh... So in autoremove's mind... It might touch on that previous
kernel and say... hm, nothing's using it now, nothing needs it to
function properly, so trash it........
Or something like that.... there...... :)
