With the transparent and userdefined checkpointing interface, there seems no checkpoint to be created
when you suspend the job or queue (and set "when" of course to x and other events). The documentation
says it should happen (man checkpoint). Also for application level interface, the defined checkpointing
script isn't executed before the migration script.

From what I know the ckpt_command is not and shall not be started for
application checkpointing. Instead migr_command is always used.

Thus I blieve this is merely an issue with documentation.

For transparent and user-level checkpointing it could be an option anyway, to get a checkpoint as late as
possible, instead of losing some computing time:

ckpt_before_kill   [yes|no]
gracetime_before_kill [<int>]

As the job is just killed, it can't be put in any script. But for application level checkpointing you are right.
