研究方向

Investigate why `sky ssh up` must be rerun after a `helm upgrade`. Start by examining the `sky ssh up` command implementation (likely in `sky/ssh.py`) and how SSH configuration is stored. Review the Helm chart files to see if upgrades reset SSH related resources. Check if there are any existing comments or linked issues in the issue #7659 discussion. Consider if the issue is related to missing post upgrade hooks or configuration persistence. Look for any recent changes in the repository that might have introduced this behavior.
