Thanks.

According to the setup.exe default package information,  
Following 41 packages forms 'a core cygwin environment':

---------------------------
Alternatives ash base-files base-passwd bash coreutils 
cygwin cygwin-doc diffutils editrights findutils gawk gdbm
Grep gzip libgdbm lidgdbm-devel libgdbm3 libgdbm4 
libncurses5 libncurses6 libncurses7 libncurses8 libreadline4
Libreadline5 libreadline6 login man ncurses run sed
Tar termcap terminfo which zlib cygwin-doc man gawk
Termcap zlib
---------------------------

In the first phase, I can think of producing a monolithic
installer for the core environment performing tasks
below:

- Create basic cygwin registry mountpoints
- untar packages
- run the postinstall script
- Create start menu items and shortcuts (optional)
- maintain setub.db (how?)

Would that be a valid cygwin installation ?

Second phase could be to introduce upgrade functionality.
