[Bug 1875548] [NEW] Live USB disk check

[C.S.Cameron]

Public bug reported:

I see that Live Ubuntu 20.04 is plagued by disk checking on boot.

Not just with Live USB but with Persistent USB also.

If not fast enough to cancel with ctl-c it starts on filesystem.squashfs
and runs until over 90% complete.

Very irritating. There have been quite a few complaints on Ask Ubuntu
already.

If it was just a run once it would not be so bad.

Is there some way to get rid of this or is it a bug we have to live
with?

Perusing Ask Ubuntu everyday for many years I have never seen anybody
ask for such a feature.

A run once filesystem check might have its uses on a Live installer
drive but is not needed on a Persistent utility drive.

The only alternative I see is to use a Full install USB drive were
automatic disk checking is not run.
