the first of what will undoubtedly be numerous newbie-level questions about UML, since i've been perusing the wealth of online docs for UML and, with few exceptions, all of it is either out of date, incomplete, wrong or suffering from broken links. my goal is to document how to start from scratch and get UML up and running on fedora 8 (and subsequently, fedora 9). so, where to begin? first, what's the difference between specifying the root filesystem at invocation time with "ubd0" versus "ubda"? here: http://user-mode-linux.sourceforge.net/ the explanation uses "ubda", while here: http://uml.nagafix.co.uk/ "ubd0" is used, as well as adding "root=/dev/ubda" even further down the page. there's no explanation as to what these differences mean, yet they all seem to work identically. help? rday -- ======================================================================== Robert P.

Perhaps this link will point you in the right direction: http://user-mode-linux.sourceforge.net/old/switches.html Jay |

I'll probably be proved wrong here, but I use ubda as ubd0 (/dev/ubda) and ubdb as swap (/dev/ubdb) (only seems to work as swap) then ubdc etc are more filesystems. Sorry If this doesn't help you, I'm no UML know-it-all. Jay |

Perhaps http://zumastor.googlecode.com/svn/trunk/doc/zumastor-howto.html#_uml will be of some use. I like writing that kind of recipe; here's one I did on a related topic: http://kegel.com/linux/jeos-vmware-player/jeos-vmware-player-howto.html And you know about crosstool :-) - Dan |
