Why en_US.UTF-8 locale is generated every time during liveCD/liveUSB
startup? See these lines in less /var/log/casper.log :

Begin: Setting up locales... ... Generating locales...
  en_US.UTF-8... done
Generation complete.
done.

Locale generation uses a lot of memory and slowdowns startup.
I think en_US.UTF-8 locale should be already generated in filesystem.squashfs and other locales should be generated during liveCD/liveUSB startup only if user chooses another language in syslinux.

It seems Ubuntu 12.04 and newer releases already contains en_US and
other en_* locales in filesystem.squashfs (they are generated during
installation of language-pack-en-base package), but script casper-
bottom/14locales doesn't check if locale isn't already generated - I
think command "localedef --list-archive" should be used for checking if
needed locale isn't already generated.

Bug description:
  I was poking around the /cow filesystem to see how much memory was
  being used and why.  The figure was higher than I expected (14M), and
  the bulk of it was due to two things:

  /var/cache/debconf - the templates are huge, but we're also storing
  two copies of them (templates.dat and templates.dat-old).  Unlinking
  templates.dat-old should immediately free up 5M of memory, at least
  until ubiquity runs.  It would be nice if we could avoid this
  entirely, though.  An md5sum check reveals that templates.dat and
  templates.dat-old are identical; if it's unchanged, then why make a
  backup?  I don't see why this file should need to change during a
  casper session

  /lib/modules - something is causing many kernel modules to be copied,
  but not all of them.  I'll attach a list.
