Hello Sergey,

I received the same results:
chef home # /tmp/tar-1.15.2-20050902/src/tar --verify --totals --create --preserve-permissions --absolute-names --one-file-system --label full.jmcdole.onefilesystem.2005-10-20 --file full.jmcdole.onefilesystem.2005-10-20.tar --verbose --listed-incremental full.jmcdole.onefilesystem.2005-10-20.snap /home/jmcdole/ >> full.jmcdole.onefilesystem.2005-10-20.log 2>&1 

chef home # grep Contents full.jmcdole.onefilesystem.2005-10-20.log

Lastly, here's the diff's of the two tars, one with and one without the --one-file-system flag:
chef home # hexdump -C full.jmcdole.2005-10-20.tar > full.jmcdole.2005-10-20.hex
chef home # hexdump -C full.jmcdole.onefilesystem.2005-10-20.tar > full.jmcdole.onefilesystem.2005-10-20.hex
chef home # colordiff full.jmcdole.2005-10-20.hex full.jmcdole.onefilesystem.2005-10-20.hex | less -r
