Comment (by rhaas):

 To clarify: are we talking about Formaline or simfactory? Formaline should
 not deal with executables or checkpoints, simfactory not with tarballs.

 I was actually going to suggest (different ticket) to make the simfatory
 executables copies instead of hard links. Otherwise changing the
 executable via a cp command (eg. when using simfactory in debugging runs
 which are the vast majority of all runs I run [other user might differ of
 course]) is rater surprising in that all hardlinked executables change
 which can in fact cause running simulations to fail (since the disk image
 that the OS used as paging store changed).

 I fully agree that checkpoints in simfactory are to large to copy but am
 not sure if the same argument applies to the <200MB of executable and
 tarballs. I tend to generate multi GB of output for even the smallest
 useful simulation so am not sure if saving 200MB is worth the added
 headache in having to deal with a more complicated and less inherently
 robust system.

 Please don't get me wrong: if others are more concerned about saving disk
 space then I can live the proposed changes, they just would not be my
 first choice.
