Following small patch fixes this and workarounds devfs related problem
which appeared in 2.4.0-test12-pre8:
when I'm logging out, devfsd tries to state /dev/vcc/[1-6] but sometimes
fails perhaps due to some race in kernel. As result devfsd quits with
error message. Retrying to state node suceeds on next attempt.
I don't know why it happens, but I guess it's related to
change in drivers/char/tty_io.c between test12-pre7 and pre8
(change to use flush_scheduled_tasks())
Hint: it seems to be easier to reproduce on slower machine (it happens seldom
on PIII-700, but very often on P200MMX)

If devfs is mounted and devfsd exists, start devfsd.

Not true. I'm pretty sure /dev/.devfsd is only created when you
mount devfs at boot time or via mount -t devfs devfs /dev in
your system initialization script. Creating /dev/.devfsd with
touch defeats the purpose of /etc/rc.sysinit example.

problem with devfsd compilation
Hi, I am trying to compile devfsd on my system running RedHat linux 7.0 (kernel 2.2.16-22). I get the error "RTLD_NEXT" undefined. I am not sure where this symbol is defined. Is there anything that I am missing on my system. Also, I applied the devfs patch to the kernel, installed the new kernel, modified lilo.conf, ran lilo and rebooted the system with the option "devfs=nomount". The system is able to mount the root file system in readonly mode. But after that when it tries to do fsck to the root file system before mounting it in "rw" mode, it fails. Looks like devfs seems to be having a problem with my /etc/fstab. My /etc/fstab has device names specified in the "LABEL=.." format. Does devfs understand LABEL=.. format ? Any help is appreciated. -hiren - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] Please read the FAQ at http://www.tux.org/lkml/

Not true. I'm pretty sure /dev/.devfsd is only created when you
mount devfs at boot time or via mount -t devfs devfs /dev in
your system initialization script. Creating /dev/.devfsd with
touch defeats the purpose of /etc/rc.sysinit example.
