Yes my mistake - sorry.

OK. Might be well for backward-compatibility - but the devfs solution

We at ROCK linux (www.rocklinux) use it for years - and never had a
problem (maybe some have - because they use the www.ibm.org/linu-docs-somewhere
approach of taring them on shutdown and untar it on bootup. Using devfsd.conf
is hust fine! (I'll try to search the archive for devfs posts ...)
