Right now, we have a problem with cyclic dependencies in core: systemd requires libblkid and libuuid (systemd-udevd) and util-linux requires libudev (findmnt, and soon uuidd [1]).
Do you run a huge SAP install? I don't run a huge SAP install. I'm not sure why anyone who doesn't run a huge SAP install cares about uuidd, but I understand your concern.
I think my sarcasm-detector is broken, there's a red light flashing that wasn't there before.
I don't like this situation and currently it is revoled by adding systemd as optdepend to util-linux. This has the side effect that in a chroot with only certain packages installed, one has to explicitly install systemd to get findmnt working. Since I've run into this situation and cyclic deps are bad, I propose the following:
Split both util-linux and systemd into libutil-linux/util-linux and libsystemd/systemd. Then we could have both util-linux and systemd depend on both libsystemd and libutil-linux.
Is this really necessary just to avoid minor problems in chroots? We used to have a libsystemd package, and subsequently ditched it. I don't see anything critical here.
It's probably the right thing to do (better than some fishy optdepend). And since I am extremely fond of findmnt, it would make me incredibly happy.
But hey, for some good news, there's already/still packages which depend on libsystemd.
Great stuff!
