initial build-vm feature Yes, mkimage-profiles is now able to build VM disk images. So far the support is pretty basic: - a single hard drive image with a single partition/FS - only stock root password is configurable - LILO is hardwired as a bootloader The resulting images tend to boot under qemu/kvm though. Please see doc/vm.txt for the warning regarding additional privileges and setup required. This was started back in February but I still hoped to avoid sudo/privileged helper (and libguestfs is almost as undistributable as can be)...

build-vm: update referenced script name It's probably a good year to get rid of this reference practice resulting in a known sort of misdocumentation over time :-/ 2015-01-04 15:45:56 +03:00			`# this script relates to features.in/stage2/stage1/scripts.d/81-make-initfs`

build-vm, tar2fs: unify kver handling No need to deduce kernel version again, just save it in a temporary file. The main reason to change what worked is that e2k kernel-image package has Linux bits named as image-$kver and not vmlinuz-$kver; the guessing logic taking all of this into account resulted in non-aesthetic patch. NB: there's a duplicating script within kernel feature; it wasn't easy to avoid this and it might differ when handling multiple kernels, I didn't think much about this now as vm images tend to ship with the sole one. 2017-08-02 15:44:57 +03:00			`[ -n "$kver" ] \|\| { echo "** unable to deduce kernel version" >&2; exit 1; }`
