Naturally not. But it seems I come from a bygone era when people
still believed in avoiding unnecessary bloat. I felt (and indeed
still feel) that a 500MB root filesystem should be more than enough.
After all, a root filesystem should contain only what is necessary
to boot the system, and repair it if things go wrong. Hell, even
the FHS agrees with me on that -- indeed it explicitly says that it is
a goal to try and keep the root filesystem as small as reasonably
possible. Sadly, those developing modern distributions seem to
have different ideas :-(

As an interesting contrast, my OpenBSD box has a 50MB root filesystem,
and doesn't come close to filling it. I know that a direct comparison
between the two isn't really possible, but even so, Linux should be
able to manage better than being an order of magnitude larger.

wrong tool for every job. -- Bruce Eckel
