This use case is covered by the password agent, which is an entirely different concept: http://www.freedesktop.org/wiki/Software/systemd/PasswordAgents/ And again, I’m not saying this won’t cause problems. It will. Your keyscripts will not magically be replaced upon upgrades. From my research, this is the most significant incompatibility between sysvinit and systemd in Debian, and this is something that could have been better dealt with. It is certainly one of the best reasons to keep sysvinit fully working for the timeframe of the jessie release. But it is something that will eventually be replaced without any significant impact on functionality and usability. In the long term, it is not a reason for keeping sysvinit available.

It puzzles me that that bug is known for 3 years yet is not marked RC, especially since it appears systemd-sysv will be pushed on dist-upgrade (#758825) as well. Adding to that the newer kernel's requirement to add hid_generic to initramfs before usb keyboards will work, I see a high risk of hard to recover boot failures.

And this someone is anti-systemd? Back in the day, udev itself was the Horrible Non-Unixy Devouring Horror that all the neckbeards were categorically opposed to. Now not even the most sociopathic curmudgeon (and there are plenty of them in the community) opposes it.

Does the current script not work with systemd? Can udev alone associate the startup of services associated with the discovery of iSCSI or LVM devices?

It is called udev. There is no strong reason to push it to init. Fine grained udev rules always did the job. In its current form, systemd brings more limitations than features for the use cases I've listed.

It is sysvinit which is fundamentally deficient in handling dynamically discovered devices.

I'll put some I know rightway here. http://anonscm.debian.org/cgit/pkg-iscsi/open-iscsi.git/tree/debian/umountiscsi.sh.init http://anonscm.debian.org/cgit/pkg-iscsi/open-iscsi.git/tree/debian/open-iscsi.init http://anonscm.debian.org/cgit/pkg-lvm/multipath-tools.git/tree/debian/multipath-tools.init I'd be interested to know how they could be adapted to systemd without a sub-shell script.
