#9 Use dump -L for live file systems

[Chris]

I am using flexbackup on FreeBSD 5.3 (installed from
the ports collection). When dumping a live file system,
it should be possilbe to pass dump the -L flag. Refer
to http://www.freebsd.org/cgi/man.cgi?query=dump&sektion=8

A workaround for now is to add the -L option manually. I added it on line 1080, see below:

$cmd .= "dump -$level ";
$cmd .= "-L ";
$cmd .= "$::dump_blk_flag ";
