Bug when image in main.tf set to Rocky Linux 10

[foglienimatteo]

My cluster deployment with Magic Castle 15.4.1 fails when I upgrade the OS image from Rocky Linux 9 to 10 (no other changes, with version works).
More specifically, puppet fails to run; the root cause seems a string comparison on the puppet file params.pp, that I think is downloaded from config_git_url = "https://github.com/ComputeCanada/puppet-magic_castle.git".
In such file, on line 480, I think the test $facts['os']['release']['major'] < '7' results in '10' < '7' == True because of lexicographic string comparison, rathern than mathematic comparison.

Rocky Linux 10 bug: $facts['os']['release']['major'] < '7' in puppet file

I don't think RHEL-like 10 is supported in Magic Castle yet

[ocaisa]

Would require work similar to ComputeCanada/puppet-magic_castle#239 for puppet to support.

[cmd-ntrf]

Alan is correct, EL10 is yet supported by Magic Castle.

The progress tracking toward EL10 support is here : ComputeCanada/puppet-magic_castle#466

We are getting close to support, and once the PR that bumps most of the Puppet modules is merged, the rest should be relatively trivial to fix.
