kernel, devfs and /proc/partitions question.
Hello,
I have some questions concerning the kernel and its devfs usage.
If i understand correctly, all kernels used for debian-installer should
have the devfs built, but not the devfs-automount stuff loaded.
My understanding was that when doing that, and booting the kernel with
no special option, then devfs is supposed to not be activated, and this
is what we will use for the sarge installed kernel.
When using the same kernel for debian-installer, we need devfs, and thus
either enable the auotmount option, or use the command line devfs=mount.
Is this correct ? What do other people do here ?
Furthermore. If devfs is not mounted, devfs should have no influence
whatsoever on the running kernel, right ?
The problem is that i am running the powerpc kernel without any devfs
option, and not built with devfs-automount, but altough the df output
seems ok, /proc/partitions seems to show the devfs volumes.
Is this the correct and expected behavior ? What do other people
(popwerpc users or not) see here ? And can this be safely ignored, or
will it cause problems later with non devfs mounted kernels ?
