Sec's questions

I have a laptop that has been installed with ubuntu 20.04 that is being used as a server. Thus I want it to never suspend.

By default it automatically suspends when the lid is closed.

As I can only access it via ssh (and there is no X installed anyway) I need to disable it via the CLI.

Multiple sites suggest using

sudo systemctl mask sleep.target suspend.target hibernate.target hybrid-sleep.target

This does indeed stop the laptop from suspending while the lid is closed, but results in systemd-logind consuming 100% cpu and continuously logging the following: (multiple times per second)

 systemd-logind[514]: Suspending...
 systemd-logind[514]: Unit suspend.target is masked, refusing operation.
 systemd-logind[514]: Failed to execute suspend operation: Permission denied

Can anyone tell me how to properly disable suspending?

If I setup a new luks volume with "cryptsetup --verbose --cipher=aes-cbc-essiv:sha256 --key-size=256 luksFormat /dev/foo /my/keyfile" it requires me to enter "YES" to actually do anything. Is there a way to skip this prompt, so I can just run it from a script?

Is there a way to easily find exactly which processes are currently "swapped out" (i.e. currently taking up my swap space).

I know that processes are dynamically swapped in and out as needed, but I'm interested in the current state they are in.

I am talking about FreeBSD here but would also be interested in a general answer for other OSs.

I found plenty of documentation on how to convert a .vmdk file to a .vdi (VirtualBox) file. But they all assume you don't use snapshots. -- Is there a way to convert the vmdk snapshots too?
