Public bug reported:
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.
