Wow! I really think that is a bug *if* it does. What makes you think
that is the case?
Ok, let me say it this way: That laptop has 2 different flavours of
kernel, the first one is rt-686-pae while the other is 486, and the
first one has a 'regular' "Linux" entry within LILO boot menu, while the
second one was designated as "LinuxOLD" entry. (Btw, that machine was
gradually upgraded to wheezy 7.9, and started as squeeze 6.0.1a some 2.5
years ago, so I forgot the initial kernel setup.) Anyway, for a long
time now there have been only such two kernel options, so I could choose
in between them. As long as I remember, during every kernel update both
kernels were updated in the same time so I could test each one
instantly. I never had any system freezing since the very beginning of
squeeze. And by looking into the /boot/ directory, I always saw the
single newest instance of each flavour. I have never seen any older
version kept there after the update. (Have I missed to look into some
other folder?)
One more thing that might be interesting: For some traditional reasons
(say, rather conservative personality), I haven't tried GRUB on that
machine. In opposite to that, I have a desktop comp running Ubuntu
(started with 10.04.x LTS and gradually upgraded to 14.04.x LTS) where I
initially had GRUB for a while. I remember that very soon GRUB menu
became filled in with a lot of kernel options, and that it kept a dozen
or more kernels there, so later I decided to install LILO and remove
GRUB. Interestingly, that Ubuntu still keeps some 7-8 older kernels
backwards (until I de-install them - I do it maybe once per year because
I do have a plenty of disk space there). Btw, /boot/grub/ sub-folder is
still there for unknown reasons, so it might be that some GRUB 'ghost'
forces it to keep older stuff :-)
