I dont really understand what is going on...
| Code: |
[root:/dev] > ll cd*
lr-xr-xr-x 1 root root 13 Dec 18 11:32 cdrom -> cdroms/cdrom0
cdroms:
total 0
lr-xr-xr-x 1 root root 34 Dec 31 1969 cdrom0 -> ../scsi/host0/bus0/target0/lun0/cd
lr-xr-xr-x 1 root root 34 Dec 31 1969 cdrom1 -> ../scsi/host0/bus0/target1/lun0/cd
|
so okay, cdrom is already linked to cdroms/cdrom0. I want it to be link to cdroms/cdrom1 instead:
| Code: |
[root:/dev] > unlink cdrom
[root:/dev] > ll cd*
total 0
lr-xr-xr-x 1 root root 34 Dec 31 1969 cdrom0 -> ../scsi/host0/bus0/target0/lun0/cd
lr-xr-xr-x 1 root root 34 Dec 31 1969 cdrom1 -> ../scsi/host0/bus0/target1/lun0/cd
|
So far so good.
| Code: |
[root:/dev] > ln -s cdroms/cdrom1 cdrom
ln: `cdrom': File exists
[root:/dev] > ll cd*
lr-xr-xr-x 1 root root 13 Dec 18 11:33 cdrom -> cdroms/cdrom0
cdroms:
total 0
lr-xr-xr-x 1 root root 34 Dec 31 1969 cdrom0 -> ../scsi/host0/bus0/target0/lun0/cd
lr-xr-xr-x 1 root root 34 Dec 31 1969 cdrom1 -> ../scsi/host0/bus0/target1/lun0/cd

devfs maintains the symbolic links, so, when you delete the symlink, devfsd recreates it. What you need to do is modify your devfsd.conf file to change the link, here's a portion of mine, you change the line with LOOKUP at the begining to point to cdroms/cdrom1
# Create /dev/cdrom for the first cdrom drive
LOOKUP ^cdrom$ CFUNCTION GLOBAL mksymlink cdroms/cdrom0 cdrom
REGISTER ^cdroms/cdrom0$ CFUNCTION GLOBAL mksymlink $devname cdrom
UNREGISTER ^cdroms/cdrom0$ CFUNCTION GLOBAL unlink cdrom
