The tag is there correctly (i.e. as you ca see in the TAGS= field, which includes systemd for both cases). My edcuated guess is that this is a result of you having a partition table on top of md, which causes the md rules in 99-systemd.rules not have ay effect on the partition block devices. Kay, Harald, could you please have a look into this? The current udev rule probably needs some updating to deal with setups like these.

Not sure, if that's the whole story: http://cgit.freedesktop.org/systemd/systemd/commit/?id=d2fff1ced447c09c6601a6617300467ccd81660b The current rules always marked all MD partitions as inactive, which does not sound right. We are not even sure if the partitions would ever get a change event later. Please try if that makes things better, as said, there might be more needed than that.

Re: [systemd-devel] Cryptsetup on FakeRAID fails with timeout
I responded too early, mdadm has caused its own set of problems: - During the boot process, the mdXpX.device don't get marked as active automatically causing X.mount based on those devices to fail. Once I get to the emergency shell, simply calling 'systemctl daemon-reload' reloads the mdXpX.device items which are now marked as active (why?). I have worked around this problem by building a new oneshot service which calls 'systemctl daemon-reload' before attempting to use the X.mount items. I also had to move the offending partitions to 'noauto,comment=systemd.automount' so that a suitable delay was put in between the mdadm setup and reloading the modules otherwise systemd-remount-fs.service wouldn't get started (for some reason)! - Cryptsetup on the mdXpX device still fails when it is called, though this time I get a more useful response other than 'timeout': Sep 23 18:06:29 alipc-desktop-ex sudo[3636]: ali : TTY=pts/4 ; PWD=/home/ali ; USER=root ; COMMAND=/usr/bin/systemctl start home-ali-m Sep 23 18:06:29 alipc-desktop-ex sudo[3636]: pam_unix(sudo:session): session opened for user root by (uid=0) Sep 23 18:06:29 alipc-desktop-ex systemd[1]: Starting Cryptography Setup for cryptmedia...
