Enabling devfs by default it debian would make a few things in the
installer easier
- no need to map device names from devfs used by d-i into old style
/dev/ names used in /target/.
- Programs in /target/ using devices can use the same config when
running within d-i and in 'chroot /target'.
It would also make a few things in Debian easier:
- LVM would work out of the box
- USB devices would work out of the box
- The devices would no longer change name when inserting new devices,
/dev/sdc would no longer move to /dev/sdd when inserting a new hard
drive earlier in the SCSI chain
It might give us a few new problems:
- Some platforms do not have working devfs support. drop or add
workaround?
- Will all kernel devices handle devfs properly?
In skolelinux, we have enabled devfs by default (by using devfsd) to
get LVM working. We haven't experienced any problems yet. I believe
enabling devfs by default in Debian would be a good thing to do.
