mini-perl, which is good enough to run a large portion of the perl
scripts, is 1MB. Consider adding a few moudles manually to it.
mini-perl is not part of any package, to the best of my knowledge. But
it is built as part of building perl

Debian has a package called vim-tiny which only depends on vim-common .
Those two packages together has a total installed-size of 1.5MB . It
lacks many of the standard options of vim, but still way better than nvi
or (yuck) busybox vi.

nano's isntalled size is 1.6MB . If you rarely use it, consider
installing nano-tiny instead, which has an installed size of 252kB .

Aternatively, just replace both with ed, which has an installed isze of
144kB :-)

Replacing apache with a lesser httpd-cgi and using php-cgi is also an option
if the program that requires PHP is mostly unused, and you want to
conserve space.
