I don't use Gnome and haven't looked into all this. Udev also doesn't appear to have a LVM-useflag. But as I do use LVM, I can't actually check. Do you have "sys-fs/lvm2" on your system?

Which is basically the task of gnome-session-manager (and > whatever is the equivalent in KDE). systemd, like any init-system, should start services. KDE has some "kde-services" like akonadi, nepomuk,... that get controlled by the kde-system internally. I would NOT want to see these controlled by systemd. These are running for the user that is logged in. Having these running for all users at once leads to the multi-user-kludge that MS Windows tries to have and for which Citrix was invented ontop of MS Windows.... We already have a decent multi-user environment, why would we want to kill that?

Try "pstree -pu" and you see all the PIDs and whenever there is a "user- switch", it also lists the new user. > And you can kill every process related to a daemon, no matter how many > forks its children process make.

I consider dbus to be part of the GUI as I don't see a reason for apache, syslog, nfs, samba,.... to be using dbus to communicate with each other. There are already well-tested and working mechanisms for communication where needed. -- Joost
