I use a script that creates LVM partitions for the root and swap
partitions, then untars a debootstrap created image to it. Of
course it makes the filesystems and mounts them first. It also
creates a default config file. From executing the command to
logging in takes about a minute. I could modify the script to
change the hostname and other settings but I don't create enough
VMs to make it worthwhile.  The install has shorewall firewall
preinstalled. If I want to modify the tar'ed version I just untar
it, chroot to it and update packages or whatever, then tar it
back up. It is easy with Debian.
