[PATCH libguestfs] build: When parsing distro from /etc/os-release, try $ID_LIKE first

by Richard W.M. Jones

The current code for working out the distro uses the ID entry from /etc/os-release, and then we map those strings into a smaller set of values (basically, what package manager to use). However it was suggested that we should try ID_LIKE first so that distros which act like other distros would work. On an Arch Linux 32 system: ID=arch32 ID_LIKE=arch See-also: https://github.com/libguestfs/libguestfs/issues/81 Thanks: S D Rausty --- m4/guestfs-appliance.m4 | 14 +++++++++++--- 1 file changed, 11 insertions(+), 3 deletions(-) diff --git a/m4/guestfs-appliance.m4 b/m4/guestfs-appliance.m4 index 9e443f151d..4e63ef4356 100644 --- a/m4/guestfs-appliance.m4 +++ b/m4/guestfs-appliance.m4 @@ -102,8 +102,16 @@ AC_ARG_WITH([distro], AC_MSG_RESULT([$DISTRO (manually specified)]) ],[ if test -f /etc/os-release; then - ( . /etc/os-release && echo $ID | tr '@<:@:lower:@:>@' '@<:@:upper:@:>@' ) >&AS_MESSAGE_LOG_FD - DISTRO="`. /etc/os-release && echo $ID | tr '@<:@:lower:@:>@' '@<:@:upper:@:>@'`" + echo "/etc/os-release:" >&AS_MESSAGE_LOG_FD + cat /etc/os-release >&AS_MESSAGE_LOG_FD + DISTRO="$( + . /etc/os-release + if test -n "$ID_LIKE"; then + echo $ID_LIKE | tr '@<:@:lower:@:>@' '@<:@:upper:@:>@' + else + echo $ID | tr '@<:@:lower:@:>@' '@<:@:upper:@:>@' + fi + )" AS_CASE([$DISTRO], [FEDORA | RHEL | CENTOS | ALMALINUX | CLOUDLINUX | ROCKY], [DISTRO=REDHAT], @@ -116,6 +124,7 @@ AC_ARG_WITH([distro], fi ] ) +AC_SUBST([DISTRO]) AM_CONDITIONAL([HAVE_RPM], [AS_CASE([$DISTRO], [REDHAT | SUSE | OPENMANDRIVA | MAGEIA ], [true], [*], [false])]) @@ -125,7 +134,6 @@ AM_CONDITIONAL([HAVE_DPKG], AM_CONDITIONAL([HAVE_PACMAN], [AS_CASE([$DISTRO], [ARCHLINUX | FRUGALWARE | ARTIX], [true], [*], [false])]) -AC_SUBST([DISTRO]) dnl Add extra packages to the appliance.

[libguestfs PATCH] guestfs.pod: document encrypted RBD disk limitation

ovirt VM image to BM

by Guilherme De Oliveira Santos

Greetings masters, I got pointed to you guys as experts on smtg I'm struggling with. I'm trying to move an ovirt vm raw image to a bm machine and though I could do it successfully using dd (got able to see and work with the partitions and the data fine), I couldn't boot the disk. It may be an issue with drivers (like the virtio drivers), but idk, and I'm wondering if someone has done smtg similar or could help somehow with the process. Really appreciate any answer on that, thanks! Gui

[PATCH] git: Add 'git-publish' config file

by Kashyap Chamarthy

The `git-publish`[1] tool is a wrapper around `git-format-patch` and `git-send-email`. It's a handy tool that automates some of the tedious aspects of manual patch submission: - Submitting a patch to the list (with a small config in place) is as simple as `git publish` - On next revisions, it automatically increments version numbers - It auto-copies the list of To: and Cc: from your previous iteration - It lets you preview/edit emails before submission - You can also use standard `git-format-patch` and `git-send-email` options with `git publish` - You can send pull requests with `git publish --pull-request` - It also provides custom hooks ... and more[2] [1] https://github.com/stefanha/git-publish [2] https://github.com/stefanha/git-publish/blob/master/git-publish.pod Signed-off-by: Kashyap Chamarthy <kchamart(a)redhat.com> --- .gitpublish | 3 +++ 1 file changed, 3 insertions(+) create mode 100644 .gitpublish diff --git a/.gitpublish b/.gitpublish new file mode 100644 index 000000000..9775dd231 --- /dev/null +++ b/.gitpublish @@ -0,0 +1,3 @@ +[gitpublishprofile "default"] +base = master +to = libguestfs(a)redhat.com -- 2.35.1
