[Bug 1032322] [NEW] Swap space allocation for large memory systems needs improvement

[Launchpad Bug Tracker]

You have been subscribed to a public bug by Robbie Williamson (robbiew):

The recipe used for automatic swap space allocation during install this
is:

100% 512 200% linux-swap
        $lvmok{ }
        $reusemethod{ }
        method{ swap }
        format{ } .

Where we currently allocate a minimum of 100% of swap (maximum 200%).
The original justification for this is that you need 100% of your memory
to guarantee hibernate works (bug #311299).    However, for servers, we
don't hibernate and often have large amounts of memory installed, i.e.
100's of GB or even TBs, and such a method wastes a lot of disk space.

I propose we do at least 100% (probably a bit more) for machines up to a
certain level of memory (4GB or less.../maybe/ up to 8GB), to ensure
client machines can hibernate.  However after that, we set some sort of
sliding scale approach that maxes out at a reasonable amount for
servers.  Experienced users can always override the settings if they
want.
