Subject: difference between gentoo=nodevfs devfs=nomount
Date: Thu, 20 May 2004 20:16:14 +0000 [thread overview]
Message-ID: <40AD120E.6020209@wanadoo.fr> (raw)
Hello everybody,
I'm a french student, and I'm very interested on udev and hotplug.
In my gentoo, there are a linux kernel 2.6.6, and no devfs flag in
kernel. I would like no more devfs and only udev. I'm wondering what
are the differences between the kernel boot option: gentoo=nodevfs
devfs=nomount. In gentoo doc, it is suggested to put devfs=nomount to
disable devfs. Moreover, I have disable RC_DEVICE_TARBALL="no", and
RC_DEVFSD_STARTUP="no" in /etc/conf.d/rc .
1) With gentoo=nodevfs, kernel stops because it cannot find my / fs .
There is no symlink in /dev (/dev/hdaX --> /dev/ide/..../partX) but
there is a rule in /etc/udev/rules.conf :
# devfs-names for ide-devices (uncomment only one)
# /dev/ide/.../{disc,cd} and /dev/{cdroms,discs}/* type names
BUS="ide", KERNEL="hd*", PROGRAM="/etc/udev/scripts/ide-devfs.sh %k %b
%n", NAME="%k", SYMLINK="%c{1} %c{2}"
2) I don't understand why use ide-cd instead of ide-scsi, with ide-cd
udev doesn't create node in /dev in order to mount cdrom. Whereas with
ide-scsi /dev/sr0 is created and I can mount it. Is ide-cd for burn cds?
3) On my second computer, i have the same config but with
nvidia-drivers. I run gdm and it works fine execept duplicated symbols
(xorg-x11) but it is impossible to switch consoles with ctrl-alt-fX, in
fact X freeze. The framebuffer doesn't work very well, i cannot obtain
vgay1 : 1024x768, maybe it is because nvidia module is not load at
kernel boot time?
Thanks in advance
Nanouck
