Re: mounting media as a normal user

# NetBSD /etc/fstab
# See /usr/share/examples/fstab/ for more examples.
/dev/wd0a               /       ffs     rw               1 1
/dev/wd0b               none    swap    sw               0 0
# /dev/wd0e             /mnt    ???     rw,noauto                0 0
/dev/wd0f               none    swap    sw               0 0
/dev/wd0g               /var    ffs     rw               1 2
/dev/wd0b               /tmp    mfs     rw,-s=1049328
kernfs          /kern   kernfs  rw

/proc      /proc        procfs rw,linux 0 0
procfs /usr/pkg/emul/linux/proc procfs rw,linux

That's my fstab printout. Still not able to use the device as a normal
non-root user.
I copied the example to etc.
Do I use chmod 766 /dev/cd0a or something to that nature?
