Beginner question: what should I verify right after install?

[OliviaBR]

After a clean installation, what are your top 5 checks before deploying apps?

I currently check networking, time sync, package endpoint, and storage health.

Would love a recommended sequence from experienced users.

Solid list already. Suggested order:
1) network + DNS
2) NTP/time sync
3) Store/package endpoint reachability
4) free space and write permissions
5) test app install and rollback

We will publish this as a pinned starter checklist.
