Re: systemd? Do not want.
Salix is much better than Slackware - all the BSDs have integrated package management, and its omission in Slackware by default is just too painful. The use of lilo instead of grub is unusual these days, as is the fact it boots without an initrd, but the use of mbootpack enables even complex Xen configurations to boot.
I did have to terminate Networkmanager with extreme prejudice - I'm sure it must be possible to get a bridge working reliably on startup using it, but life is too short. It's also on a system which just runs a lot of VMs and will never run X, or add/remove physical network adapters (virtual is a different matter).
