no devfs when using custom kernel

i have mdk9.1
when running on the original kernel, i have this message "Mounted devfs on /dev" when booting and the devfsd daemon is started
i needed to compile a custom kernel, but the devfs is not mounted and devfsd not started
first do i need the devfs? second why is it not mounted even i have devfs=mount in the lilo.conf?

devfs is part of the kernel, you must have just not enabled it. you might want to check the template config files for the original kernel to see what they had set up for it.

You do not need devfs - the classic way to do things is to make device special files in /dev by hand (read warning below though)

To use devfs, be sure to configure your kernel properly before compiling.

To make device nodes, use mknod.

mknod name type major minor

name: name of device file, like hda2
type: 'c' for character devices, 'b' for block device (no quotes around 'c' or 'b')
major, minor: device numbers

A list of device numbers can be found at, or in your kernel source. You do not need to make all devices, just the ones you use.

Warning: if you want to keep using devfs, which is a virtual filesystem containing the relevant special files, you can not place special files in /dev.

thanx both of you

looks like when my system runs without probs (yet) with no devfs i do not need it ;-)

well i could not find the devfs enabling option in the config menu, but comparing the .config files showed the difference

thanx again
