It won't cause damage if the partition is mounted read-only, which it
is if ext2fs found it marked dirty.

Just run fsck before you do your `fsysopts / --writable'.

You can't.  ext2fs.static handles many magic things including the
default pager.  It looks bigger than it is... all that size is really
functionality and the default pager.

You can try stripping it, if you really want to conserve disk space,
but I'm not sure that'll actually make its memory footprint smaller.

Don't `ls -l /dev', just `ls' it.

This is the likely one.  There are probably still a few port leaks.

$ portinfo PID | wc -l

counts the number of ports.  There used to be a port leak in the proc
server that would leak 3 ports per exec.  I'm not sure if it's been
fixed yet.

One is the default pager... I'm not sure of the other.
