# UFS:
# For ufs, it might be false one, since if the Id=a5, it's FreeBSD slice
# E.g. The disk sdb has 3 slices (sdb1, sdb2, sdb3), and slice sdb1 contains partitions sdb5, sdb6, sdb7, slice sdb2 contains partitions sdb8, sdb9, sdb10, and sdb3 contains partitions sdb11, sdb12, sdb13. As shown in the following.
# Then blkid will show /dev/sdb1 as ufs, but it's only slice, we only have to save the first 16 sectors by "dd if=/dev/sdb1 of=slice1-table.dd bs=512 count=16"
# Therefore if blkid shows "ufs", we have to dig more.

# Some notes:
# First priority is to use blkid to get filesystem, 2 reasons:
# (1) Since parted seems to have problem with ntfs in some case:
# LC_ALL=C parted -s /dev/hdb p
# Model: VMware Virtual IDE Hard Drive (ide)
# Disk /dev/hdb: 8590MB
# Sector size (logical/physical): 512B/512B
# Partition Table: msdos
#
# Number Start End Size Type File system Flags
# 1 32.3kB 8579MB 8579MB primary ntfs boot
#
# [root@drblrhvmnet101 ~]# LC_ALL=C parted -s /dev/hdb1 p
# Error: Can't have a partition outside the disk!
#
# (2) Moreover, the method in get_from_parted does NOT work for LV in LVM... blkid can solve the problem. The weakness is blkid does not provide size info, but it's not so used very often in clonezilla, and normally size is not important when cloning.
