Option to disable health-checker in Grub

[idnovic]

Hello,

I would like to be able to do the following:

force disable the health-checker via a grub flag.
My reasoning is the that currently selinux is in a failed state in MicroOS.

But what happens if I check selinux with the health-checker?
An endless cycle of reboots. (theoretically, I did not try it)

From a security perspective I may want to check the state of selinux during start up.
Let me disable the health-check for debugging purposes if needed.

I did find the health_checker_flag variable.
But I am unsure what happens if i manually set it.
The system uses this variable.
So i think that an manual override should not use the same variable.

Just a short comment about how health-checker is working:

If a health-checker test should fail, then the system will be reset to the previous snapshot. If that snapshot also fails, then the system will be rebooted once more, and if the tests still fail, then the system will switch to emergency mode (i.e. it is probably better to not start into a known broken system, but open an emergency shell).

Making it possible to disable health-checker via kernel parameters for debugging purposes might still make sense though.
