Has anyone though of (or worked on) on implementing some kind of partition support for block devices? What I mean is that block devices such as hda have a major,minor number for the device itself, then different minor numbers for each individual partition. UML on the other hand uses one major number for the ubd devices, and differentiates between the devices with the minor number. There doesn't appear to be any support for devices for each partition on the device. -- - Matt Clay - Cowboyz.com - (503) 241-1990 |

Why you would want to partition something like that is beyond me. However, you can sub-divde block devices using LVM - Just use the /dev/ubd/X device as your physical volume, then create some logical volumes out of that, and use them appropriatly. -- David Coulson http://davidcoulson.net/ d...@vi... http://journal.davidcoulson.net/ |

I would like to have the option of installing Linux w/o needing to make any special exceptions during the installation procedure (such as having to install to non-partitionable block devices). > However, you can sub-divde block devices using LVM - Just use the > /dev/ubd/X device as your physical volume, then create some logical > volumes out of that, and use them appropriatly. I don't know much about LVM, but I'm guessing that using it requires some kind of configuration or setup inside the UML before it can be used. If that's true, it won't help with installing Linux, unless the installation procedure supports LVM. -- - Matt Clay - Cowboyz.com - (503) 241-1990 |
