Will the Gnu 'tar' released with SuSE 6.1 have support for bzip archives
(often names like foobar.tar.bz2, compare to foobar.tar.gz)?
So that you can like, extract etc. with commands like:

    tar ytvf foobar.tar.bz2
    tar yxvf foobar.tar.bz2

Last time (december 1998) I check Gnu's tar, the 'y' flag still had to
be put in with a patch from the bzip2 site.

(fyi: here's my install log of how i built a bzip2 aware Gnu tar
 december 1998 (corrections are welcome, but it works for me a 100%),
 '+' is your prompt:

    Installed bzip2-0.9.0c and patch for Gnu tar 1.12 (reinstall).
    Bzip2 is far a better compressor than gzip, and is rapidly gaining
    popularity, url: <A HREF="http://www.muraroa.demon.co.uk/";><A HREF="http://www.muraroa.demon.co.uk/</A">http://www.muraroa.demon.co.uk/</A</A>>
    Also reinstall Gnu tar 1.12 with a patch which adds the bzip `y' flag.

    1. bzip2

    + make

    The 4 compare tests must be ok. Install as follows:

    + mv bzip2 bzip2recover /usr/local/bin/.
    + mv bzip2.1 /usr/local/man/man1/.
    + ( cd /usr/local/bin && rm -f bunzip2 bzcat )
    + ( cd /usr/local/bin; ln -s bzip2 bunzip2; ln -s bzip2 bzcat )

    2. Gnu tar 1.12 patch.

    Get the bzip patch for Gnu tar 1.12:
      <A HREF="http://www.muraroa.demon.co.uk/gnutarpatch.txt";><A HREF="http://www.muraroa.demon.co.uk/gnutarpatch.txt</A">http://www.muraroa.demon.co.uk/gnutarpatch.txt</A</A>>
    following instructions "4. Using bzip2 with tar" from
      <A HREF="http://www.best.com/~dfetter/Bzip2-HOWTO/Bzip2-HOWTO-4.html";><A HREF="http://www.best.com/~dfetter/Bzip2-HOWTO/Bzip2-HOWTO-4.html</A">http://www.best.com/~dfetter/Bzip2-HOWTO/Bzip2-HOWTO-4.html</A</A>>
    and given here. Unpack Gnu tar-1.12 source and then:

    + cd tar-1.12/src
    + patch < ../../gnutarpatch.txt
    + cd ..
    + ./configure && make && make install

    Flag for bzip is always `y' where you would use `x' for gzip:

      tar ycvf foo-4.2.tar.bz2 foo-4.2    (create  a bzip-ped tar file)
      tar yxvf foo-4.2.tar.bz2            (extract a bzip-ped tar file)
)
