#v407 fix for floppy drive icon.
#v409 gparted create ext3 part. failed, fixed by making /etc/mtab a symlink.
#120103 shinobar: need 'silent' option for ntfs-3g, avoid err msgs, permissions lost when copy.
#130203 change probedisk2 to probedisk.

#mount-FULL, umount-FULL, losetup-FULL are the full versions.
#The Busybox versions of mount and umount are available but only by:
# # busybox mount ...
# # busybox umount ...
#mount and umount are now scripts.
#if an ntfs partition, puppy uses user-mode ntfs-3g driver.
#the mount and umount scripts allow seamless mounting and unmounting of ntfs f.s.
