For build/packaging for multiple distributions (or just a distribution
that you don't really like to use), you may want to take a look at user
mode linux.  It gives you a lot of what vmware does without the cost of
vmware.

Quick start, (.deb of uml is available too):

$ wget http://telia.dl.sourceforge.net/sourceforge/user-mode-linux/user_mode_linux-2.4.18.36um-0.i386.rpm
$ su
# rpm -Uvh user_mode_linux-2.4.18-36um-0.i386.rpm
# exit
$ wget http://telia.dl.sourceforge.net/sourceforge/user-mode-linux/root_fs.rh72.pristine.bz2
$ bunzip2 root_fs.rh72.pristine.bz2
$ chmod 400 root_fs.rh72.pristine
$ linux ubd0=root_fs_rw.rh72,root_fs.rh72.pristine \
	eth0=tuntap,,fe:fd:0:0:0:1,192.168.0.1
...
login: root
password: root
# ifconfig -a
---> be sure that you have eth0 up if not:
# ifconfig eth0 192.168.0.2 netmask 255.255.0.0 broadcast 192.168.255.255 up
---> then
# route add default gw 192.168.0.1
# mkdir /usr/src/samba
---> this assumes that you have NAT enabled or nfsserver is

# mount nfsserver:/export/samba /usr/src/samba
# cd /usr/src/samba/samba-2.2.25
# ./configure && ...


Presumably you could add an init script that makes it possible to
automatically mount the directory that has the samba source, then run
some magical build script that is on that share.  When it has finished
running the script, it halts the uml instance.  Your packages should be
on the nfs server.

With each day's build you could use a fresh root_fs_rw.rh72 so that you
are sure that you are building it based upon a clean distribution.

See http://sourceforge.net/projects/user-mode-linux/ for more details.
