Change subject: add -d parameter when umouning in mk_sysprep_floppy
......................................................................


Patch Set 1: I would prefer that you didn't submit this

(1 inline comment)

have you actually seen this problem happen? mount(8) says

 Since  Linux  2.6.25  is supported auto-destruction of loop devices and
 then any loop device allocated by mount will be freed by  umount  
independently on /etc/mtab.

this explains why I've never had a problem with this script.

I do not deeply resent asking destruction of the loopback explicitly, I would 
just want to know if the problem is actual or theoretical.

unrelated to this patch:
$FLOPPY_DIR is never defined! it should be dropped to allow floppy creations 
with relative paths.
