Yes, it is a userspace program that the kernel is very aware of.

the param CONFIG_DEVFS_MOUNT=1 needs to be set in the kernel .config and recompiled. The kernel will mount devfs at boot with this option.

How can I explicitely activate it ?


It is an option that must be compiled in the linux

executable. You can

check if it it compiled in yours with

./linux --showconfig | grep DEVFS
and look for CONFIG_DEV_FS=y

If not, you may have to use another binary or compile your own, the devfs option is to be found under the "File System" menu.

The kernel image linux-2.4.19-5 from the uml kernel page has this option set.


$ linux --showconfig | grep DEVFS
CONFIG_DEVFS_FS=y
# CONFIG_DEVFS_MOUNT is not set
# CONFIG_DEVFS_DEBUG is not set

So it seems the devfs is builtin, but it doesn't automatically mount.
Are there any command line options to mount it ? (/etc/fstab doesn't do it)
