 |
|
I have a wicked little problem with devfsd:
The settings in devfsd are not applied to dev:
-I have a DVD drive and a cdrw , both IDE resp. hdc and hdd
-I have scsi generic+cdrom compiled in as a module, ata cdrom directly
-In my /dev I find entries for : ./cdroms/cdrom0 and cdrom1 and also sg0 and sr.
I can read from both devices and the cdrw is seen as a scsi device
-kernel bootline is:
| Code: |
kernel /boot/bzImagedef root=/dev/hda6 hdd=ide-scsi vga=0x314 mem=nopentium
|
-Hdd is defined as a scsi device as you can see
-In my modules.autoload there the module ide-scsi is loaded.
-users are member of the cdrw group
I want /dev/dvd and /dev/cdrw to show up but they don't
Furhtermore , users cannot write to sg0 for the audiocd io slave for instance or cd writing.
It has worked before and this is a more or less fresh install!!
Anyone have a clue?
my relevant devfsd part looks like this:
| Code: |
****CLipped****
# Enable module autoloading. You may comment this out if you don't use
# autoloading
LOOKUP .* MODLOAD
# Uncomment this if you want permissions to be saved and restored
# NB: Do NOT change the following!
# Do not do this for pseudo-terminal devices
REGISTER ^pt[sy]/.* IGNORE
CHANGE ^pt[sy]/.* IGNORE
CREATE ^pt[sy]/.* IGNORE
DELETE ^pt[sy] IGNORE
REGISTER .* COPY /lib/dev-state/$devname $devpath
CHANGE .* COPY $devpath /lib/dev-state/$devname
CREATE .* COPY $devpath /lib/dev-state/$devname
DELETE .* CFUNCTION GLOBAL unlink /lib/dev-state/$devname
RESTORE /lib/dev-state
# You can force default like this :
# PERMISSIONS owner_and_group access_mode
# ALSA/OSS stuff
# Comment/change these if you want to change the permissions on
# the audio devices
LOOKUP snd MODLOAD ACTION snd
LOOKUP dsp MODLOAD
LOOKUP mixer MODLOAD
LOOKUP midi MODLOAD
REGISTER sound/.* PERMISSIONS root.audio 660
REGISTER snd/.* PERMISSIONS root.audio 660
# Give the cdrw group write permissions to /dev/sg0
# This is done to have non root user use the burner (scan the scsi bus)
REGISTER ^sg0$ PERMISSIONS root.cdrw 660
# General note for the following auto creation of symlinks:
#
# If you change the device that the symlink points to,
# you should also remove the symlink before restarting
# devfsd
# Create /dev/cdrom for the first cdrom drive
#LOOKUP ^cdrom$ CFUNCTION GLOBAL mksymlink cdroms/cdrom0 cdrom
#REGISTER ^cdrom/cdrom0$ CFUNCTION GLOBAL mksymlink $devname cdrom
#UNREGISTER ^cdrom/cdrom0$ CFUNCTION GLOBAL unlink cdrom
# Create /dev/dvd for the second cdrom drive
# (change 'cdroms/cdrom0' to suite your setup)
LOOKUP ^dvd$ CFUNCTION GLOBAL mksymlink cdroms/cdrom0 dvd
REGISTER ^cdrom/cdrom0$ CFUNCTION GLOBAL mksymlink $devname dvd
UNREGISTER ^cdrom/cdrom0$ CFUNCTION GLOBAL unlink dvd
# Create /dev/cdrw for the first cdrom on the scsi bus
# (change 'sr0' to suite your setup)
LOOKUP ^cdrw$ CFUNCTION GLOBAL mksymlink sr0 cdrw
REGISTER ^sr0$ CFUNCTION GLOBAL mksymlink $devname cdrw
UNREGISTER ^sr0$ CFUNCTION GLOBAL unlink cdrw

oops! I spotted that the default devfsd.conf file has a few typos:
/cdrom/cdrom0 has to be /cdroms/cdrom0
The "s" is added, now the devices are regged.
Mind you, It was the default conf file. I missed the error because it used to be ok.
Only the sg0 is not writable for cdrw users, but I might add the ide-scsi into the kernel instead of a module. maybe that fixes it. |

If the CDRW is only accessible by root you may need to add your users to the cdrw group to allow access.

That was already taken care of as stated in the first post 
It may be that devfs is loaded before the ide-scsi module.
the device is not there yet and the settings are not applied then? |
