On the porter machines /proc is mounted, also inside the chroots:
null            /proc           linprocfs  rw               0       0
null            /srv/chroot/sid/proc        linprocfs rw    0      2

It is possible that this is a linuxism, but if this should not be used on
bsd, wouldn't it be better if the proc filesystem is NOT available on the
porter boxes?  Or at least document it so that package maintainers can find
it. I do not see proc mentioned here
http://wiki.debian.org/Debian_GNU/kFreeBSD_FAQ
or here
http://glibc-bsd.alioth.debian.org/porting/PORTING
When I log onto the hurd porter box, I get some links to porting issues,
which I think is a great idea (but they also don't mention proc...)

Thanks for the patch. This works on the porterbox, so I hope it will also
work on the buildds.
