Ok, I see.

Well, it's possble, but we need a script/Makefile guru
to implement it...

I'll add option variables like INSTALLIMGMB/USBIMGMB/EMUIMGMB etc.

I also thought to put pre-installed binary packages into custom
liveimage, but I gave it up because:
- pkg_add(8) doesn't provide options to prepare spec files as install(8)
  and maintaining spec files manually is a bit pain
- some pacakges might update lines in /etc/shells or /etc/master.passwd etc
- useradd(8) doesn't handle DESTDIR environment

Instead, I've prepared an "afterboot(8) installation image" that includes
necessary binary packages and custom /etc/skel files etc. and
just run a dumb script as following:
on qemu (the target liveimage is on wd0 and afterboot image is on wd1)
so that I can build custom liveimages including all necessary
package binaries and a prepared user on my build host.

If you already have maintained spec file, you could simply add
your binary .tgz set (which also include spec file in /etc/mtree) into
SETS variable (mentioned in distrib/common/bootimage/Makefile.bootimage)
might also work.
