FreeBSD pre-mount script for gnop device?

  • 772

How do I run a script in FreeBSD before filesystems are mounted?

I want to install a gnop device and mount it (no, not for ZFS). Is there any canonical place where I can put a gnop create ...?

  1. Create an rc script, e.g. 

    #!/bin/sh

# PROVIDE: gnop disks
# BEFORE: fsck

. /etc/rc.subr

name="gnop"
start_cmd="${name}_start"
stop_cmd=

gnop_start()
{
    local disk="/dev/da1"
    /sbin/gnop create -S 4096 "$disk" || err 1 "Creating gnop on $disk failed"
}

load_rc_config $name
run_rc_command "$1"

    where /dev/ada1 This could be extended to created multiple nop devices based on a configuration in rc.conf.
