[Sisuite-devel] [PATCH] Fix --unit % in si_prepareclient using parted

[Greg Fiumara]

parted 1.8.1 (perhaps older versions as well) place a space before the
partition number when printing partitions. As such, the current
regular expression will never set $end_of_last_partition_on_disk to a
non-zero value, resulting in a perl illegal division by zero error
when running `si_prepareclient' with the `--unit %' switch. This
patch simply allows there to be whitespace before the first digit.
Patch applied to SystemImager 4.1.6.
