I suspect that Jim is suggesting that the test should just try to create the file, and if it happens to be running on a filesystem that supports sparse files bigger than 16TB, then it can run the full test, otherwise it can mark it as "missing support" - rather than creating and mounting a loopback device as part of the test suite. -- Colin Watson [[email protected]] _______________________________________________ parted-devel mailing list [email protected] http://lists.alioth.debian.org/mailman/listinfo/parted-devel
