If the download takes m minutes and unpacking and unarchiving tar.gz takes another n minutes, what difference does it make for this workflow when instead m + p minutes are spent for download + unpacking and unarchiving tar.bz2 or tar.xz? -- Stefan Richter -=====-==-=- --=- -===- http://arcgraph.de/sr/ -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
