Fair enough. > That won't make umounting a tmpfs /dev any more rational to do though > (but just a tmpfs that happens to contain a device node is perhaps not > the right test for what to avoid, and manual specification when that > fails to DTRT isn't a great alternative.) I'm not sure there *is* a truly correct test for what to avoid, given the nature of what's being done at swapoff, but there may well be better heuristics. I don't want to derail this thread though, so we can take that up separately at a later date. Good luck fixing the crash! -- IDL
