blkid: make PART_ENTRY_* tags optional (add --no-part-details)
blkid(8) returns information from partition table also for empty
partitions. This is necessary for example for udev, but it could be
confusing if you care about on-device content only.
Default:
# blkid -p /dev/md0p1; echo $?
/dev/md0p1: PART_ENTRY_SCHEME="dos" PART_ENTRY_UUID="6d8796b1-01" PART_ENTRY_TYPE="0x83" PART_ENTRY_NUMBER="1" PART_ENTRY_OFFSET="2048" PART_ENTRY_SIZE="204800" PART_ENTRY_DISK="9:0"
0
With --no-part-details:
# blkid -p /dev/md0p1 --no-part-details; echo $?
