Checking a service after restart
Confirm the process, listener, local health endpoint, and one external request. A green process alone is not the whole test.
FIELD NOTES
Small systems, kept dependable.
Short notes on Linux administration, service health, backups, and practical network operations.
Backups should be boring
Keep configuration snapshots small, dated, and easy to inspect. Recovery is clearer when the archive has a narrow purpose.
Leave room on the root volume
Package updates and temporary build files need working space. Alert before the filesystem becomes an emergency.
