Hello together, I recently stumbled over cdrom_id opening the device with the O_EXCL flag set, if it is not currently mounted:
"fd = open(node, O_RDONLY|O_NONBLOCK|(is_mounted(node) ? 0 : O_EXCL));" The effect of this is that automatically mounting a cdrom sometimes results in "resource busy", if "change" uevents of the devices are processed by udevd while the automounter (udisks or something different in my case) is currently trying to mount the device triggered by a previous "add" or "change" uevent. I've to questions to this issue. Maybe someone of you can help me: 1. Is there any particular reason why cdrom_id should open the device exclusively (especially since it is not opened exclusively when it is already mounted)? 2. If there is any good reason to keep this behavior: How is the best way for an automounter to deal with this? Retry? Something different? Thx in advance for valuable input.
