I have boot media that are each set up to boot a variety of systems that have widely different RAM sizes, from 1 GiBytes to 64 GiBytes for the aarch64 examples of this. This has lead to having multiple swap partitions of various sizes so that I can have total swap spaces that are somewhat under the recommended maximum sizes for the amount of RAM in each of those systems that a given media can boot. It would be nice if I could have just one swap partition on a given boot media, one that is more than sufficient in size for all but the biggest RAM system --but to then be able to tell the system to just use up to the recommended swap space size and to ignore any extra swap space in the swap partition. If such could be done, I'd no longer use multiple swap partitions at the same time in order to get to a desired total for the system at hand at the time. Of course, that still leaves what to do when multiple swap partitions are enabled if such a "ignore what would be extra" mode was also enabled. As I'd not use such, I've no specific recommendations to make that would make any difference to my use. === Mark Millard marklmi at yahoo.com
