Live images want to be able to create some symlinks to loop devices that are used for the system so that they can later be identified. We add the udev rules to do so in the initramfs when we're setting up the loop devices. But since the loop config has OPTIONS=last_rule, the symlinks never get created
ok, but please do not create 128 loop devices :)
oh, and you can always place your rules in 49-myloop.rules
(In reply to comment #1) > ok, but please do not create 128 loop devices :) We use a number of them during live CD boot... although I guess since we only have 8 by default, n+8 isn't that bad. So probably would just choose 16. (In reply to comment #2) > oh, and you can always place your rules in 49-myloop.rules Nope -- have to append to an existing file so that SELinux doesn't get in the way. No policy is loaded in the initramfs so files get created as unlabeled_t; reading files labeled unlabeled_t is (rightfully) denied. We can't set the context in the initramfs because the kernel won't let you set security xattrs that it doesn't know about.
