[Libguestfs] [PATCH] p2v: make-disk: rely on os-release for host distro detection

Instead of assuming the latest Fedora version if /etc/redhat-release is available, or the latest Debian with /etc/debian_version, use only /etc/os-release. The possible name of the virt-builder template is created by concatenating $ID and $VERSION_ID, which is generally a better guess than what previously done, and better matches the host OS. This affects only the case when os-version is not specified as command line argument. --- p2v/virt-p2v-make-disk.in | 8 ++------ 1 file changed, 2 insertions(+), 6 deletions(-) diff --git a/p2v/virt-p2v-make-disk.in b/p2v/virt-p2v-make-disk.in index bdf7fd96e..ee65716f2 100644 --- a/p2v/virt-p2v-make-disk.in +++ b/p2v/virt-p2v-make-disk.in @@ -122,12 +122,8 @@ if [ $# -eq 1 ]; then else # If osversion was not set, then we must guess a good value # based on the host distro. - if test -f /etc/redhat-release; then - osversion="$(virt-builder -l | sort | - @AWK@ '/^fedora-[1-9]/ {print $1}' | tail -1)" - elif test -f /etc/debian_version; then - osversion="$(virt-builder -l | sort | - @AWK@ '/^debian-[1-9]/ {print $1}' | tail -1)" + if test -f /etc/os-release; then + osversion="`. /etc/os-release && echo ${ID}-${VERSION_ID}`" fi if [ "x$osversion" = "x" ]; then echo "$program: unable to guess a suitable os-version." -- 2.17.2
