Pull request overview
This PR establishes Azure Linux (CBL-Mariner) 4.0 support paths in LISA by extending GRUB configuration handling, making CBL-Mariner package-manager detection more resilient via lazy initialization, and ensuring modetest can be installed on Azl 4+.
Changes:
- Add an Azl4 GRUB config implementation (RHEL/BLS-aware) with Azure Linux–specific UEFI GRUB paths.
- Lazily initialize the CBLMariner DNF tool selection to avoid early
dnf_tool_unavailable-style failures, and add Azl 4+ systemd-logind drop-in handling forKillUserProcesses. - Install
drm-utilson CBLMariner 4+ to enablemodetestusage.
