Hello=0A=
=0A=
Wonder if there should be any consistency in 'mdconfig' parameter parsing w=
hen run from the shell and when run through 'rc.conf'.=0A=
=0A=
I hoped I could copy'n'paste the parameters from the command line to 'rc.co=
nf'=2C reboot and enjoy. No.=0A=
=0A=
=0A=
Works fine from command line:=0A=

mdconfig -f /usr/local/zfs/backups -u 0=0A=
=0A=
=0A=
Fails in 'rc.conf'=2C the file is surely there:=0A=

Would anyone bother make 'rc.conf' more relaxed about the parameters and th=
