This pull request makes a small change to the disk space check logic in the
check_disk_space_availabilityfunction during the installation of the Azure Monitoring Agent. The minimum required free space for the/etcdirectory has been reduced from 500 MB to 5 MB.In security-hardened environments (e.g., those following CIS Benchmarks), it is standard practice to implement Filesystem Segmentation, where directories like
/etc,/var, and/optare mounted on separate logical volumes or partitions. The current 500 MB requirement is prohibitive for these environments. A dedicated/etcpartition is often sized conservatively (e.g., 1-2 GB total), and requiring 500 MB of free space forces administrators to unnecessarily resize system partitions. Since the Azure Monitoring Agent primarily uses /etc for small configuration files (storing binaries in/optand logs in/var), the actual footprint in/etcis negligible (typically kilobytes).Checking for 5MB maintains a safe buffer for config generation while resolving installation blockers on partitioned systems.
