Package: usbmount Version: 0.0.21 Severity: important Hello,
Usbmount is run directly from the udev rule engine and the rule engine must wait for usbmount to complete. This is wrong. If usbmount is not going to run as a daemon I imagine it should at least detach before doing any work. >From the developers of udev: http://www.spinics.net/lists/hotplug/msg05325.html ---------------------------------<snip>------------------------- Udev's rule engine is not the right place to hookup mounting of arbitrary filesystems, or configure non-trivial network settings like DHCP, or start system daemons, or run any other programs that runs for an unpredictable amount of time. Udev rules should only be used to identify or initially configure hardware, but never to execute system management jobs or things that involve policy or need error handling like filesystem checking or mounting. Running such programs from udev rules will block related events, and might render the entire system unusable. To ensure timely event execution, udev forcefully kills all programs it has executed from rules, and which take longer than 30 or 60 seconds to finish, and mounting and checking disks can take much longer than that. Udev can send events to services which can act on device changes though. An auto-mounter service can listen to block device events and take the appropriate actions, such a service will not block udev's operations for an unpredictable time. Udisks and systemd for example work like that. Mounting filesystems is just not simple enough to do that in udev, you need a real service to do that properly. Udev rules are just not the right tool for the job, and very likely never will be. ---------------------------------<snip>------------------------- -- System Information: Debian Release: 6.0.3 APT prefers stable APT policy: (500, 'stable') Architecture: i386 (i686) Kernel: Linux 2.6.32-5-686 (SMP w/2 CPU cores) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/bash Versions of packages usbmount depends on: ii lockfile-progs 0.1.15 Programs for locking and unlocking ii udev 164-3 /dev/ and hotplug management daemo ii util-linux 2.17.2-9 Miscellaneous system utilities Versions of packages usbmount recommends: ii pmount 0.9.23-1 mount removable devices as normal usbmount suggests no packages. -- no debconf information -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
