Are there really many of them? I don't believe Debian or OpenBSD does
this. I think they rather patch the packages to allow setting the

It seem that it can, if the pkg_create command runs under the same
fakeroot environment. As an example, I tried creating a tar file with some
setuid program as a regular user:
bash-2.05a# mkdir fakeroot
bash-2.05a# chown root:root fakeroot
bash-2.05a# cd fakeroot
bash-2.05a# touch login
bash-2.05a# chown root:root login
bash-2.05a# chmod 4555 login
bash-2.05a# ls -l login
-r-sr-xr-x 1 root root 0 Jun 30 18:05 login
bash-2.05a# cd ..
bash-2.05a# tar cf - fakeroot | tar tvf -
drwxr-xr-x root/root 0 2005-06-30 18:05:11 fakeroot/
-r-sr-xr-x root/root 0 2005-06-30 18:05:11 fakeroot/login
(This is under Debian GNU/Linux, I have yet to try under NetBSD.)
Isn't this all that's needed?
