It overhauled my media server.
I hadn't set it back up after moving. I gave OpenClaw ssh credentials and it updated the OS and packages, then couldn't get back in after a restart.
I plugged in keyboard and screen and it was stuck at boot, couldn't mount a drive.
I sent OpenClaw screenshots and it told me to type in journalctl commands. Then it had me modify fstab so boot could continue.
After that, OpenClaw could get back in on its own. It found the drive I'd been using had 1300 bad sectors and was going to die. It saw that another drive was perfectly healthy. It said the bad disc sectors were all early and probably just filesystem metadata and my files were probably fine. It copied 1.5Tb to the newer drive and restored everything.
I probably would have thrown the whole box out, as I hadn't used it in a year and wasn't looking for a project like that.
