There is nothing wrong with using X11 at runlevel 3. The only thing that can't be present is a display manager (KDM, XDM, GDM etc). If it is, it is wrong, and doesn't comply with the unix standard (don't remember exactly which, but I studied it when working for Conectiva). > The only consistency seems to be 0, 1 and 6 -- although many > distros differ on a "maintanence" run-level between 0 and 1. The standard is there. If a distro chooses not to follow it, you can be very sure it will have acceptance problems. When I have time later today (or tomorrow), I'll give out the standard I'm mentoning and will give you a proper reference. Sorry I can't provide it from the top of my head. - -- Rodrigo Barbosa <rodrigob at suespammers.org> "Quid quid Latine dictum sit, altum viditur" "Be excellent to each other ..." - Bill & Ted (Wyld Stallyns) -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.0 (GNU/Linux) iD8DBQFCn1m6pdyWzQ5b5ckRAi3aAKC2nNnZv9ccL6UElGV59gWoiL67MwCgr/bu vwXU6qBIP2iFmhnCT578KtM= =/wCY -----END PGP SIGNATURE-----
