Allow migration from gdm to gdm-container in one go #5
Description
As a user of MicroOS with GNOME desktop I need to remove gdm (and patterns-microos-desktop-gnome). gdm-container will refuse to work before the new snapshot is active meaning I need to reboot without a GUI. I assume it could work in one go except for the package checks currently in place.
- Maybe the state of the pending snapshot can be used for reference?
- Prompt to prepare the snapshot with the right dependencies, which then is known to work after a reboot.
- If all else fails, an argument or variable to set, to skip the dependency check.
