Excellent idea -- although I was bearing in mind that sometimes people
_do_ want to keep around (and sometimes use) more than one kernel.

One trick Linux users have employed all the way back to early days is to
keep one known-good-for-sure kernel setup around and never fool with it, 
leaving it available in one's bootloader for quick system repair in case
the latest'n'greatest has a problem.

Yeah, people might be accumulating linux-headers-* packages' files, too,
and those ought to be part of housekeeping.  But that seemed not very
important in recent context because they go into /usr/src/ and
/lib/modules, not /boot.
