From different sources, we can see that "Automatically mount at boot" support for devfs should be disabled. The guide says that it should be enabled while it is "required" for Gentoo Linux. Reproducible: Always Steps to Reproduce: 1. 2. 3.
Ersin: Plz be more specific, what are the 'different sources'? so we can investigate it
" Make sure to disable the devfs options of automatically mount at boot time and Debug devfs." http://www.isi.edu/~weiye/system/guide/devfs.html "Be sure not to enable "Automatically mount at boot time" or "Debug devfs"." http://www.cs.ucla.edu/~roy/devfsSetup.html
as you can see from the installation doc: (Required for Gentoo Linux) [*] /dev file system support (EXPERIMENTAL) [*] Automatically mount at boot according to the links you provided, please notice that this is a gentoo system, not redhat :P however, devfs can be unabled, just keep reading the doc..
I'm pretty sure that it doesn't hurt to have it automatically enabled, knowing that it is done this way since the beginning that I started with Gentoo. I can investigate to see if it has a negative effect to disable it in the beginning somewhere tonight, but: - we have a devfs script that starts devfsd in the beginning. If devfs isn't mounted, this initscript will probably fail - if you don't want to use devfs you have to explicitly set "gentoo=nodevfs", which makes me think that devfs *really* is needed - I can't find a script that explicitly _mounts_ devfs, meaning that, if there is indeed no such script in Gentoo, than devfs will never be mounted.
consolefont refuses to start without devfs, devfsd refuses to start (ofcourse:), halt.sh refuses to continue, hdparm errors out. If you don't want to use devfs, don't select it _and_ append "gentoo=nodevfs" to the kernel parameters as described by the installation guide.
