Subject: Re: Linux 2.6.33-rc7

I've looked up the GNU tar history, just in case this is relevant:

[1] 1994-11-16 Version 1.11  -z --gzip
[2] 1999-02-01 Version 1.12  -y --bzip2
[3] 2000-10-24 Version 1.12+ -j --bzip2
[4] 2007-10-17 Version 1.20+    --lzma
[5] 2008-06-26 Version 1.20+ -J --lzma
[6] 2008-06-26 Version 1.20+    --lzop
[7] 2009-03-04 Version 1.21+ -J --xz
