sysinstall did this in its magic installFixupBase() routine as bogon #4.
I've no idea if bsdinstall replicates all the same post-install
fixups. Hmm, my fresh 9.0 system has no /compat or /usr/compat, so
this seems to be missing. I think the package should keep installing
to /compat, but I don't really think the package should set the policy
of symlinking /compat to /usr/compat. That should be in the install if
/compat doesn't already exist.
FWIW, for my own home-rolled installer on 8 I use the following shell
function to simulate installFixupBase() (note, the installed system is
mounted at /mnt, and this runs from the "outside" not in a chroot into
# Fixups from installFixupBase() in sysinstall's install.c
chmod 0755 /mnt/etc
mkdir -p /mnt/var/db
chmod 0644 /mnt/var/db/mountdtab
ln -s usr/compat /mnt/compat
chroot /mnt /bin/sh -c newaliases
mtree -deU -f /mnt/etc/mtree/BSD.root.dist -p /mnt
mtree -deU -f /mnt/etc/mtree/BSD.var.dist -p /mnt/var
mtree -deU -f /mnt/etc/mtree/BSD.usr.dist -p /mnt/usr
