+                     GNU/Linux equivalents of WIM format
+
+What's the equivalent way to capture the filesystem of a GNU/Linux operating
+system into an archive file?  You have a few options:
+
+SquashFS:
+       SquashFS (http://squashfs.sourceforge.net/) provides a compressed,
+       read-only filesystem for Linux, and it's probably the closest equivalent
+       of the WIM format and better designed.  Although you can't mount
+       SquashFS read-write, when wimlib does this for WIM files it's really an
+       illusion since the WIM isn't actually modified until the image is
+       unmounted.  Multiple top-level images in SquashFS files are not
+       supported, although nothing stops you from just putting each image in a
+       separate directory.
+
+FSArchiver:
+       FSArchiver (http://www.fsarchiver.org/Main_Page) is not widely used, but
+       it appears to have some features quite similar to the WIM format.
+
+Tar:
+       The well-known tar format can usually capture a UNIX filesystem just
+       fine, and compressing the tar file produces a good compression ratio
+       (better than WIM, especially if using XZ compression), but there is no
+       support for random access, file deduplication, multiple images per
+       archive, or extended attributes.
+
+Zip:
+       Zip shares some features with WIM but is not designed to store entire
+       filesystems.
+
+7z:
+       The 7z format has some nice features but is unfortunately not designed
+       with UNIX in mind.
