I had portage in a squashfs before too - that was nice :)
That's also the reason I had /usr/portage /var/cache/edb and /var/db/pkg
on one filesystem - all together in the squashfs :)
Because one day my / became full I moved /usr/src onto that partition
too (it was now on a reiser3fs). All fine, and other partitions less
fragmented... until I moved to ext4.

Now I have a SSD, and it's simpler than squashfs'ing and still fast.
distfiles is on a HDD (Thinkpad notebook with ultrabay - love it) and
compilation on tmpfs (8GB RAM, so no problems). I always have like 8
kernel trees lying around, so there are already like 400k files... For
various reasons I like to keep my stuff on separate partitions -> my
system is distributed over 6 partitions and my personal data over 3
partitions :)

That inode-trouble was actually quiet interesting ;)
