Now I download a fiel system --Gentoo-2006.1/Gentoo-2006.1-x86-root_fs.bz2 from
uml.nagafix.co.uk. I still use v2.6.15, after install modules, I change
nothing, just.

devfs was excluded since at least 2.6.13, IIRC (the code was in but was
disabled via Kconfig). I don't remember whether the last kernel with devfs
was 2.6.12 or 2.6.13.
However, if you use a UML image from uml.nagafix.co.uk, you will not need to
enable devfs - and on existing images creating the device node correctly
after loop-mounting works.

It was probably deleted some time ago - the netlink device is a 2.0 interface
supported for the whole 2.2 cycle (maybe 2.4, because I remember such an
option). There are few chances that you need that option however (if you have
a program needing it, a newer version surely exists since ages).
