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]). 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. [1] http://www.spinics.net/lists/util-linux-ng/msg08699.html

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.

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. But hey, for some good news, there's already/still packages which depend on libsystemd.

I think my sarcasm-detector is broken, there's a red light flashing that wasn't there before.

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.

Great stuff!

And now it's lsblk, too. We could get a sane dependency chain without circles now - or wait until all of util-linux is broken.

Sadly, I didn't get to this yesterday and I spent most of today flying cross-country. Because we never ditched the libsystemd provide on systemd, we can do this piecemeal. I'm pushing a split of util-linux into testing tonight, and I'll handle the libsystemd/systemd split tomorrow or Wednesday when systemd 211 is released. As discussed on IRC, this is only going to be a runtime split. libutil-linux will only contain the dynamic libs for libuuid, libblkid, and libmount. Similar for systemd -- libsystemd, libudev, and the compat libs.

Much to my dismay, this is now done.

New depends introduce error during base installation, libutil-linux needs coreutils first else no install is found. I cannot get coreutils installed before util-linux so this is really annoying. greetings tpowa -- Tobias Powalowski Archlinux Developer & Package Maintainer (tpowa) http://www.archlinux.org tpowa@archlinux.org

That's a packaging mistake: the install= should only be in util-linux, not libutil-linux.
