That's why I added the -b option to grml-live:

So right now I've the following grml-live chroots on the build

# ls -d1 *(/)

Only selected updates take place in the chroots and I don't recreate
the chroots from scratch for rc2/stable release but use grml-live
with the -b option to update the ISO only.

Related to your question, one nifty feature for grml-live is on my
todolist: support creation of a chroot which is based on an existing
release ISO - so you don't even have to build the system from
scratch but can base your own ISO on an existing (known to work)

We use git for the version controll stuff, make-kpkg for building
our kernels and module-assistant for all the addon packages.
