Run maintenance tasks outside the OS
- maintboot runs commands outside of the current OS,
with exclusive access to the system and hardware.
This can be useful to run maintenance tasks, like repartitioning, in a controlled environment.
Maintboot builds an appliance on the fly from a list of packages (using supermin). It then loads the appliance with kexec, bypassing the bios, and runs the maintenance script in that new context.
See github.com/g2p/maintboot for installation and usage instructions.
