Set VLM Configuration saves a setting in the genera-config partition, and the
setting is in force from the next boot on: on formeo, genera.timeZone saved from
Genera was in force after the reboot. The GRUB entry “Genera bare metal (base configuration)”
boots with VLM.conf alone and keeps the saved settings for later, and Revert VLM Configuration
from that boot removes a bad setting. Both verified on formeo, the second through the GRUB
entry.
