Architecture: any Platform: all Section: lib Depends: e2fsprogs-common (= ${Source-Version}), ${Shlib-Depends}, Description: Block device ID library The blkid library efficiently allows fsck, mke2fs, e2fsck, and tune2fs to be able to look up LABEL and UUID filesystem specifiers without needing to search all of the devices in the system. Instead, the device is looked up in a cache file, and then verified to make sure the blkid cache is correct.
