Can I install molly-guard on a pve node?

[nrodriguez]

I'd like to install molly-guard on my pve nodes to prevent accidental reboots. Can I do it and being sure it doesn't break anything?

Thank you!

Never used it, but it is in the Debian repository. Which means that if it does break anything it should be easy to remove.

Define "accidental reboots".
User Via ssh? Install it.
User via gui? Don't know.

yes, mainly

At least once in your life, you’ll reboot the wrong system or run rm -rf /. It’s a rite of passage.

Usually, you won’t make that mistake again. Since only root can reboot the system, this package won’t prevent malicious reboots - root can always override or remove the barrier.

The package also has a high likelihood of interfering with normal PVE operations, such as generating an unexpected interactive prompt when the cluster needs to fence a node or when someone tries to reboot from the UI. Since this integration hasn’t been officially tested, you won’t get a “go ahead and install it” response.

Try it at your own risk.

That's what I was afraid of

I do install molly-guard on all of my systems, since 15 to 20 years I guess. (Edit: actually I do not know how old that tool is...) This includes all of my PVE and PBS.

Nevertheless: ymmv...
