[Bug 1875548] Re: Its not easy to determine how to skip the filesystem check

[Jay Michael]

Forget "quiet", it's whether "fsck.mode=skip" is the last thing on
the kernel command line.

     There is no disk check if there is something after
"fsck.mode=skip".  I tried "quiet".  Then I tried "nomodeset" instead.

     I tried putting a blank at the end of the line.  That was *not*
enough to make the "fsck" stop the disk check.  I was using the GRUB2
editor, so maybe it would have worked if I really added a blank at the
end of the line in the grub.cfg file.

     Also, Ctrl-C does *not* abort the disk check.  Given the way the
display crawled through a flock of files before saying it was on
squashfs, I'm pretty sure I hit the Ctrl-C before it had started on
squashfs -- It just did not pay attention.

Title:
  Its not easy to determine how to skip the filesystem check

Status in casper package in Ubuntu:
  Fix Released

Bug description:
  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.
