Has it ever happened to you that you typed "tar xzf" out of reflex just to
notice seconds later that the file is a bz2 file?
Happens to me all the time. Irrational as it may be, that is (or was) the
major reason why I preferred tar.gz over tar.bz2.
Anyway, it's over now. I just patched tar to use bzip2 if the z option is
used and the extension of the file provided is .bz2.
Just apply the attached patch instead of the normal gnutarpatch.txt used
by LFS. My patch incorporates the normal LFS patch so you won't notice any
difference (unless you happen to come across a gzip file with .bz2
Note that the patch just tests the extension which means that it only
works if you use "f" or "--file" to read from a file and only if the file
has the .bz2 extension. If you read from tape or stdin or the file has any
extension other than .bz2, the patch does not take effect and tar will
just behave as usual (i.e. choose gzip if you provide the "z" option.
Note also that auto-detection only affects the "z" option, not the "y"
