With 3.4-stable updating '/etc' can/should be done using mergemaster
instead. Otherwise you seem to have followed the recommended procedure.

You can't do quite what you ask for but almost.
If you look in /usr/src/Makefile.inc1 you will find
some flags for 'make' to control what is/isn't built/installed.
For example: 'make -DNOSHARE -DNOINFO -DNOGAMES installworld'
will skip all manpages (and everything else that goes into /usr/share)
and all .info files and also the stuff in /usr/games.
You can also add -DNOPROFILE to avoid installing the profiled libraries.
That should leave a pretty minimal system.

Minor bug. AFAIK it is *supposed* to work with at least /usr/src mounted
read-only. I don't think it does work though :-(
