Package: debian-handbook Severity: wishlist Tags: patch Thomas Goirand <[email protected]> sent me the attached patch to suggest the usage of yum instead of rpmstrap (in the section concerning Xen).
This should be included in the next edition of the book covering wheezy. (It probably applies to the current squeeze version but it's new content and thus should be pushed in the next major edition and not in the already released book) There's some further work to do: <programlisting> should be used instead of <screen> for simple listings, a </para> is missing, indentation is not correct, and some other markup is missing. We should also think about where to best include it. Cheers, -- Raphaël Hertzog ◈ Debian Developer Get the Debian Administrator's Handbook: → http://debian-handbook.info/get/
