Hi

For some time now I have been having a problem with ext3 and htree.

I use Gentoo, with portage as package system.  My root is on ext3
without htree, and my portage tmp/build directory is on another
drive with ext3 and htree.

Now, when you install something, it unpacks and compile and then
install it to the build root on the tmp partition (ext3 with htree),
and then 'merge' it to / (ext3 without htree) from that build root.

Every time I get the following when it 'merge' the installed image
to /:

Basically, the .tmp file for the manpage 
(/space/var/tmp/portage/perl-5.8.0-r10/image/usr/share/man/man3/Hash::U
til.tmp) gets created as a directory that points to some other dir on
the ext3 with htree partition.

I can recreate this every time.  I can try a few things to try and
figure this out.

Specs:
   P4 2.4 with Asus P4T533-C
   linux-2.5.64 (also with all the previous, and 2.4 ...)
