Hm, so mdadm changed it's udev rules files between wheezy and jessie: /lib/udev/rules.d/64-md-raid.rules → /lib/udev/rules.d/63-md-raid-arrays.rules /lib/udev/rules.d/64-md-raid-assembly.rules But mdadm (in jessie) ships it's own initramfs-tools hook /usr/share/initramfs-tools/hooks/mdadm which is supposed to copy that rules file into the initramfs. Did you maybe not rebuild the initramfs after installing mdadm? I suppose that should happen automatically. In any case, this looks like something which should be handled in the mdadm package and I'm inclined to re-assign this bug, unless the mdadm maintainers disagree (CCed). As for /usr/share/initramfs-tools/hooks/udev, I guess we should drop the copy rules for the following files - 64-md-raid.rules (mdadm, replaced by 63-md-raid-arrays.rules, 64-md-raid-assembly.rules) - 60-persistent-storage-lvm.rules (lvm2) - 55-dm.rules (lvm2, renamed to 56-lvm.rules) - 60-persistent-storage-dm.rules Does anyone see a good reason why we should copy the rules files for lvm2, dmsetup and mdadm, when those packages ship correct udev hooks themselves? -- Why is it that all of the instruments seeking intelligent life in the universe are pointed away from Earth?
