Code Issues Proposed changes

Re-read the partition table with partx -a

Browse Source 
Re-read the partition table with 'partx -a', rather than 'partx -u'.

This should fix an timing issue where the bootloader installation
fails to mount the EFI partition from a whole disk image since it
is not yet aware of the new partitions (observed with both, the
iscsi and the direct deploy interface).
