I would like some help in determining the parsing rules for device names.
For instance, there is obviously a naming pattern at work for
ad0 ad0f ad0s4 ad1e ad1s3 ad2d ad2s2 ad3c ad3s1
ad0a ad0g ad1 ad1f ad1s4 ad2e ad2s3 ad3d ad3s2
ad0b ad0h ad1a ad1g ad2 ad2f ad2s4 ad3e ad3s3
ad0c ad0s1 ad1b ad1h ad2a ad2g ad3 ad3f ad3s4
ad0d ad0s2 ad1c ad1s1 ad2b ad2h ad3a ad3g
ad0e ad0s3 ad1d ad1s2 ad2c ad2s1 ad3b ad3h
rad0 rad0f rad0s4 rad1e rad1s3 rad2d rad2s2 rad3c rad3s1
rad0a rad0g rad1 rad1f rad1s4 rad2e rad2s3 rad3d rad3s2
rad0b rad0h rad1a rad1g rad2 rad2f rad2s4 rad3e rad3s3
rad0c rad0s1 rad1b rad1h rad2a rad2g rad3 rad3f rad3s4
rad0d rad0s2 rad1c rad1s1 rad2b rad2h rad3a rad3g
rad0e rad0s3 rad1d rad1s2 rad2c rad2s1 rad3b rad3h
but what is it? Ultimately, I would like to mechanize the result, so
that I could take a name such as /dev/rad1c and say useful things about
it, as:
/dev/ad1c corresponds to partition "a" of unit "1" of the raw "ad"
(ATA disk) device. See ata(4) for more information.
If anyone out there is very familiar with the /dev entries and would
like to help with this effort, please contact me.
