I remotely upgraded the protectli vp2420 firewall appliance from 7.4 to 7.5 (amd64), and the upgrades went smoothly. However, the reboot showed 7.4. Had bsd.upgrade, etc. created.
I then attached a monitor and keyboard to this appliance and ran sysupgrade again, this time around the upgrade went fine, and it booted up in 7.5. I am curious to understand why my remote upgrade attempt did not produce the desired result, while local upgrade with keyboard/monitor did. Any pointers will be helpful. Thanks in advance. -ag
