Depending on kernel version used, the system can hung when trying to mount the extended partition (not the logical one) as it is a holder for other partitions and does not have a filesystem in it. To avoid this to happen we just mount partitions when these are using known filesystems so it does not try to mount a partition for an unsupported filesystem.
