[edit] Storing file metadata via pseudo file
File metadata such as user/group name or ID along with file permissions is a common trait among Unices and their native filesystems. While this feature has been carried over to Tar, preservation of original metadata contents has been limited. [1] Since circa 4.6 release of squashfs-tools, it is theoretically possible to create a compressed filesystem with original metadata via the use of pseudo file.[2] This does not include hard links, which means any hard links will need to be converted to sym(bolic) links.
There are other limitations with this hack, such as (but are not limited to):
- The likely loss of original user/group names, it will be stored as ID which consists of numbers,
- Ambiguous user/group name translation when storing multiple extracted archive contents, e.g. G(roup)ID 0 which is typically reserved for "root" on modern Unices is shared as "wheel" on older Unices,
- Tedious pseudo file creation when the contents of Squashfs image contains several of extracted archive contents, e.g. a FTP dump but without inclusion of compressed files.[3]
