Task ipv6 grub disable fails for grub1

[ferdinand-it]

The task notified in

ansible-ipv6/tasks/ipv6-grub-disable.yml

Line 30 in 3d71113

- Grub2-mkconfig

fails because we don't have grub2-command on the servers.

Do you have a nice solution to execute the ansible.builtin.command "update-grub ; grub-mkconfig -o /boot/grub/grub.cfg" instead of "grub2-mkconfig -o /boot/grub2/grub.cfg" instead in https://github.com/juju4/ansible-ipv6/blob/master/handlers/main.yml#L32 if there is no grub2 installed?

Per https://www.gnu.org/software/grub/grub-legacy.htmlM
"GRUB Legacy is not actively developed any longer. Only bugfixes will be made so that GRUB Legacy can stil be used for older systems."

Which environment are you using?

You can set/keep ipv6_grub_disable to false and handle specifics in your own playbook if really requiring grub-legacy but advise to update to current grub2

In Ubuntu 22.04 LTS (which is pretty new), there seems to the only "grub-mkconfig" , but not "grub2-mkconfig"

grub-mkconfig --version
grub-mkconfig (GRUB) 2.06-2ubuntu7

but it looks like its v2 anyway?

[juju4]

yes, it seems I missed a change
from quick look to pkgs.org, it seems only redhat family is using grub2-mkconfig and alpine/ubuntu grub-mkconfig
https://centos.pkgs.org/7/centos-aarch64/grub2-tools-2.02-0.86.el7.centos.aarch64.rpm.html
https://debian.pkgs.org/11/debian-main-amd64/grub-common_2.06-3~deb11u1_amd64.deb.html

should be fixed with 686a94e
Please confirm.

Reviewing this and recent github actions, it seems github runner images have no grub and as the result, this handler is not tested properly when disabling ipv6 at grub level.
Added it in github workflow default-bare and confirmed same issue (https://github.com/juju4/ansible-ipv6/actions/runs/4902164514/jobs/8753845966).

It seems that like binary, folders have been reverted to grub too, probably as no more grub1 package/folder.
/boot/grub2 path is coming from grub package, not the role.
Implemented workaround symlink.
That seems to do the trick.
Please confirm.
