Reduce rebuild frequency for SL Micro test images

[ktsamis]

Problem

SL Micro test images in IBS project systemsmanagement:sumaform:images:microos are rebuilt too frequently (often daily), which causes all available patches to be pre-applied during the build. This leaves no patches available for testing patch installation in smoke tests.

Impact

• Patch installation tests fail on SL Micro 6.0 and 6.2
• Cannot validate patch mechanism functionality
• Requires test workarounds (package downgrade/re-patch)

Current State

Version	Image Last Built	Patches Available	Status
SL Micro 6.0	June 18, 2026	0	Too frequent
SL Micro 6.1	Oct 18, 2025	175	OK (build failing)
SL Micro 6.2	June 17, 2026	0	Too frequent

Proposed Solution

Reduce automatic rebuild frequency for stable SL Micro versions in IBS:

• Current: Rebuilds on every upstream package change (daily)
• Proposed: Weekly or bi-weekly scheduled rebuilds

This allows patches to accumulate between builds, enabling proper testing of patch installation.

IBS Project

• Project: systemsmanagement:sumaform:images:microos
• Packages: SL-MicroOS60, SL-MicroOS62
• Project URL: https://build.opensuse.org/project/show/systemsmanagement:sumaform:images:microos

Alternative Solutions

1. Maintain two image variants:

   • slmicro62o-stable - rebuilt weekly for testing
   • slmicro62o-latest - rebuilt on every change for development

2. Disable automatic rebuild triggers for stable versions
