Here they are.
libc_svn.diff
I think this could go into debootstrap svn without further testing.
extra_svn.diff
Add the --extra-{mirror,suite,include} options; needs review and testing.
extra-dependencies.pl
This file is useful to find packages to feed the --extra-include
option (but its result needs manual tuning, as you can see in
kbsd-debootstrap.sh comments).
This doesn't look to me freebsd-specific, but I think this should go
to the wiki instead of svn.
kbsd-debootstrap.sh
This script is a useful example to understand how to call debootstrap
with --extra-{mirror,suite,include} options for kfreebsd-i386.
This should go to the wiki.
Hope this helps,
Luca Favatella
