The rule generator is part of udev, not udisks.
In order to rule out some corner cases. And this is still same with latest udev (and to be sure, udisks too) ? Have you tried emerging udev with --noconfmem (emerge --noconfmem -1 sys-fs/udev) and running etc-update? Made sure there are no stale files in /etc/udev from time it didn't properly use /lib/udev (I can't reacall how that went again really ...)
Try udev-182.
I hit the same bug with sys-fs/udev-182-r3. It may be related to linux-3.3. The existing persistent rules are ignored, but (as opposed to the original submitter) the rule generator doesn't even write the file if I delete it and retrigger the uevents. I have debugged a bit further by stracing udevd. Result: it runs the write_cd_rules with the following environment (I prepended "env -i" for you to be able to run this easily and censored the actual serial number for privacy reasons): env -i "ACTION=add" "DEVLINKS=/dev/cdrom /dev/disk/by-id/ata-MATSHITA_BD-RE_UJ242_CENSORED" "DEVNAME=/dev/sr0" "DEVPATH=/devices/pci0000:00/0000:00:1f.2/ata2/host1/target1:0:0/1:0:0:0/block/sr0" "DEVTYPE=disk" "ID_ATA=1" "ID_ATA_SATA=1" "ID_ATA_SATA_SIGNAL_RATE_GEN1=1" "ID_BUS=ata" "ID_CDROM=1" "ID_CDROM_BD=1" "ID_CDROM_BD_R=1" "ID_CDROM_BD_RE=1" "ID_CDROM_CD=1" "ID_CDROM_CD_R=1" "ID_CDROM_CD_RW=1" "ID_CDROM_DVD=1" "ID_CDROM_DVD_PLUS_R=1" "ID_CDROM_DVD_PLUS_RW=1" "ID_CDROM_DVD_PLUS_R_DL=1" "ID_CDROM_DVD_R=1" "ID_CDROM_DVD_RAM=1" "ID_CDROM_DVD_RW=1" "ID_MODEL=MATSHITA_BD-RE_UJ242" "ID_MODEL_ENC=MATSHITA\\x20BD-RE\\x20UJ242\\x20\\x20\\x20\\x20\\x20\\x20\\x20\\x20\\x20\\x20\\x20\\x20\\x20\\x20\\x20\\x20\\x20\\x20\\x20\\x20" "ID_REVISION=1.00" "ID_SERIAL=MATSHITA_BD-RE_UJ242_CENSORED" "ID_SERIAL_SHORT=CENSORED" "ID_TYPE=cd" "LVM_SBIN_PATH=/sbin" "MAJOR=11" "MINOR=0" "SEQNUM=2487" "SUBSYSTEM=block" "TAGS=:seat:uaccess:" "USEC_INITIALIZED=17991381937" /lib/udev/write_cd_rules The write_cd_rules prints this to stderr: /devices/pci0000:00/0000:00:1f.2/ata2/host1/target1:0:0/1:0:0:0/block/sr0 not supported by path_id. by-id may work. So I guess this is the problem: the path ID changed between kernels, and the path_id program has not been updated. I edited /lib/udev/rules.d/75-cd-aliases-generator.rules in order to always run write_cd_rules with the by-id parameter: # these rules generate rules for the /dev/{cdrom,dvd,...} symlinks ACTION=="add", SUBSYSTEM=="block", ENV{ID_CDROM}=="?*", ENV{GENERATED}!="?*", PROGRAM="write_cd_rules by-id", SYMLINK+="%c" LABEL="persistent_cd_end" End result: it wrote the rules, but did not use them immediately. They were in effect after one more "udevadm trigger", but this also resulted in an extra copy of the generated rules.
This is no longer a problem with new udev, like 198, because the rule_generator was removed
