Hi All, My limited contribution to the udev issue sounds like this:
(main source: http://git.kernel.org/?p=linux/hotplug/udev.git;a=blob;hb=HEAD;f=README) In my understanding there are only a couple of requirements the above website mentions which are (possibly) not met in T2: 1) Groups and users „The system must have the following group names resolvable at udev startup: disk, cdrom, floppy, tape, audio, video, lp, tty, dialout, kmem. Especially in LDAP setups, it is required, that getgrnam() is able to resolve these group names with only the rootfs mounted, and while no network is available.” In my T2 (trunk) installation the following groups are not there: cdrom, floppy, tape, lp, dialout, I am not sure that groups ’tape’ and ’dialout’ are really needed, however in the above README that is explicitely stated. I have noticed that also group ’uucp’ and user ’vcsa’ are claimed to be missing by udev. 2) /dev/tmp “Very early in the boot process, the /dev/ directory should get a 'tmpfs' filesystem mounted, which is populated from scratch by udev. Created nodes or changed permissions will not survive a reboot, which is intentional.” The only item in /etc/fstab which may seem similar is: none /dev/shm tmpfs defaults 0 0 At this point I am not sure where exactly the problem lies. My guess would be either /dev/tmp (instead of /dev/shm) is expected by udev or /dev/shm is created too late (-> I am also not sure what exactly “very early [in the boot process]” menas, I deduce from the context that in any case it should be done before udev be loaded. The fact is that a) udev-event several times claims /dev/tmp-x-y missing before entering the runlevel (in my case) 3 b) some process claims during boot process, immediately before entering runlevel 3 missing /dev/null I am not expert in kernel programming and in the boot process, so I can not judge with certainty that all these facts are connected, however they seem to be. best regards, helasz ----------------------------------------------------------- If you wish to unsubscribe from this mailing, send mail to [email protected] with a subject of: unsubscribe t2
