Ok, I've rechecked and nothing has been removed, but the logic has changed. In the past we would just blacklist all other devices then normal block devices, so for example we would blacklist device-mapper devices 'dm*', or software raid devices 'md*' and so on. How in factory the logic has change to, if the device is not 'sd*' or 'cciss*', etc. then totally dont do nothing, thats why in the past it worked and now doesn't. Past: KERNEL=="fd*|mtd*|nbd*|gnbd*|btibm*|dm-*|md*|zram*", GOTO="persistent_storage_end" Now: KERNEL!="loop*|mmcblk*[0-9]|msblk*[0-9]|mspblk*[0-9]|nvme*|sd*|sr*|vd*|xvd*|bcache*|cciss*|dasd*|ubd*", GOTO="persistent_storage_end"
