Description of problem: Currently, get-e2uuid gets filesystem UUID via "tune2fs -l". However, this doesn't work for JBD(journaling block device): whenever you try to get uuid of a JBD, you get a error that tells "Filesystem has unsupported feature(s)". In another way, UUID could be gotten via blkid, for both JBD or filesystems such as ext2/3/4. So it would be better to replace "tune2fs -l" with "blkid" in the implementation of get-e2uuid.
