Bug#703593: squashfs4 support

[Trent W. Buck]

Package: file-roller
Severity: wishlist
Tags: upstream

Squashfs4 is a compressed archive format that can EITHER be mounted as
a loopback read-only filesystem OR it can be treated as an archive
like tgz or zip -- using "unsquashfs foo.sq" to extract some/all
files, or with -ls / -ll to list the contents.

I've been cheerfully using squashfs with CLI tools for some time, but
some of my managers are more comfortable with a GUI archiver -- I
think file-roller is what they use.  It would be great if file-roller
could create and open squashfs archives.


PS: a little background - squashfs3 is an older variant that you can
probably ignore.  squashfs4 initially used zlib from compression;
newer tools/kernels also support LZMA2 and LZO.  AFAIK squashfs-tools
does not provide a library to link to, just mksquashfs and unsquashfs.
Also note those two are very picky about the order of their arguments.
