From 6aa260af122ce445c2b41c2ce5f487724feea917 Mon Sep 17 00:00:00 2001 From: Ludovic Courtès Date: Sat, 8 Nov 2014 14:49:13 +0100 Subject: vm: Fix 'vm --full-boot' to produce a sufficient disk image. * gnu/system/vm.scm (system-qemu-image/shared-store): Add #:disk-image-size and #:full-boot? parameters and honor them. Pass '#:copy-inputs? full-boot?', and change #:inputs argument. * guix/scripts/system.scm (system-derivation-for-action): Pass #:disk-image-size to 'system-qemu-image/shared-store'. * doc/guix.texi (Invoking guix system): Mention use of '--image-size' in conjunction with '--full-boot'. --- doc/guix.texi | 12 +++++++++--- 1 file changed, 9 insertions(+), 3 deletions(-) (limited to 'doc/guix.texi') diff --git a/doc/guix.texi b/doc/guix.texi index 2da956cc73..bc839ecbbb 100644 --- a/doc/guix.texi +++ b/doc/guix.texi @@ -4151,9 +4151,15 @@ Build a virtual machine that contain the operating system declared in The VM shares its store with the host system. -On GNU/Linux, the default is to boot directly to the kernel.
