[Libguestfs] [PATCH v2] appliance: use ID_LIKE as a fallback for SUSE distro detection

All SUSE distros have a ID_LIKE=suse, including the fake one used for building that has a ID=Dummy value. Without reading ID_LIKE on SUSE distros, the generated appliance packagelist is not correct. This fix reads ID_LIKE as a fallback if ID contains nothing. --- m4/guestfs_appliance.m4 | 10 +++++++++- 1 file changed, 9 insertions(+), 1 deletion(-) diff --git a/m4/guestfs_appliance.m4 b/m4/guestfs_appliance.m4 index fbba3373f..788afbd36 100644 --- a/m4/guestfs_appliance.m4 +++ b/m4/guestfs_appliance.m4 @@ -99,8 +99,16 @@ if test -f /etc/os-release; then DISTRO="`. /etc/os-release && echo $ID | tr '@<:@:lower:@:>@' '@<:@:upper:@:>@'`" AS_CASE([$DISTRO], [FEDORA | RHEL | CENTOS],[DISTRO=REDHAT], - [OPENSUSE | SLED | SLES],[DISTRO=SUSE], + [OPENSUSE | SLED | SLES | SUSE],[DISTRO=SUSE], [ARCH],[DISTRO=ARCHLINUX]) + dnl All SUSE-based distros have ID_LIKE containing 'suse', check for it if + dnl ID wasn't helpful. + if test -z "$DISTRO"; then + DISTRO_LIKE="`. /etc/os-release && echo $ID_LIKE`" + if echo $DISTRO_LIKE | tr " " "\n" | grep -i "^SUSE$"; then + DISTRO=SUSE + fi + fi elif test -f /etc/debian_version; then DISTRO=DEBIAN if grep -q 'DISTRIB_ID=Ubuntu' /etc/lsb-release 2>&AS_MESSAGE_LOG_FD; then -- 2.13.2
