Unfortunately, they're not grouped together.  What I'm doing (which is
probably a little crazy) is turning jails into packages so that I can
very easily upgrade them on my remote systems.  So I have a basejail
package which is the dependency for my smtp-jail package, which includes
the mounts into the basejail, etc.  So it's essentially the freebsd base
permissions (and subsets for the thin jails) which of course aren't
grouped at all, and also involves thousands of files.

I ended up using mtree (as suggested by Freddie Cash), having the build
system that creates the jails and their dist-files take the mtree spec
for the jail and include it in the package, and then as a
pkg-post-install script I made it put the permissions back via mtree -u. 

My other option was to take the makeplist target and alter it.  I found
the generate_plist() function in Mk/Scripts/check-stagedir.sh, which
uses find and sed to create the plist.  I was going to add a "stat" in
there, with the formatting of

stat -f "@(%Su,%Sg,%OMp%OLp) %N"

so that I ended up with the plist with the correct permissions on every
file. I'm pretty sure that would have worked, but the mtree solution
suggested by Freddie worked really well, so I just stuck with it.
