Here's my modified ruleset: BUS=="scsi", PROGRAM="/sbin/scsi_id -d %N -s %p -g -u" RESULT=="20004cffffe0e0976", NAME="dsk0_%n", OWNER="root", GROUP="root", MODE="0700", OPTIONS="last_rule" RESULT=="SSEAGATE_ST336807LC_3KT0CTTM00007530YTR2", NAME="dsk1_%n", OWNER="root", GROUP="root", MODE="0700", OPTI$ And here's the results: (There is actually a small difference. I now dont have a block-device for dsk0, partition 1. /dev/disk0_1 has become a character device.)
