# There are a number of modifiers that are allowed to be used in the NAME or PROGRAM fields.
# They provide the following subsitutions:
# %n - the "kernel number" of the device.
#      for example, 'sda3' has a "kernel number" of '3'
# %k - the kernel name for the device.
# %M - the kernel major number for the device
# %m - the kernel minor number for the device
# %b - the bus id for the device
# %c - the return value for the CALLOUT program (note, this doesn't work within
#      the PROGRAM field for the obvious reason.)
# %D - use the devfs style disk name for this device.
#      For partitions, this will result in 'part%n'
#      If this is not a partition, it will result in 'disc'

Ok, I'll agree with you. Care to make up a patch for this > kind of feature? Yes, I can try. There was no way to tell not to do anything so I created one. Errors are signalled via negative return values, so I thought that a positive, non-zero one could mean to ignore the device. I don't like it but perhaps you have a better solution. 2004-01-10 11:55:28 +03:00			`# device mapper creates its own device nodes`
