Bug #2403: newfs -E doesn't handle /dev/serno device names properly

Author: Francois Tigeot
Status: New
Priority: Low
Target version: 

Trying to run this command fails:

  newfs_hammer -E -L USR_OBJ /dev/serno/00000000112233445566

  Device:/dev/serno/00000000112233445566 (kern.cam.da.rno/00000000112233445566.trim_enabled) does not support the TRIM command
  usage: newfs_hammer -L label [-Ef] [-b bootsize] [-m savesize] [-u undosize]
                    [-V version] special ...

The only trim_enabled sysctls id are of the form

It seems newfs -E only expects drive names to be of the form /dev/daX
TRIM options in other utilities such as fdisk or disklabel may have the same issue
