Oops - you are correct. %k is kernel name, and %n is number. In any
case, if you are only using one tape device, you could create a rule
to give you /dev/tape and /dev/ntape. What I would do is create a
file in /etc/udev/rules.d called 15-local.rules and put in two lines:
KERNEL=="nst0", BUS=="scsi", SYMLINK+="ntape", MODE="0660"
KERNEL=="st0", BUS=="scsi", SYMLINK+="tape", MODE="0660"
At least, I normally use tape for the rewinding device and ntape for
the non-rewinding device. The name used is not critical as long as
your rules come before the default rules listed above.
