Though honestly, I've never used Or PLAN9_MOUNT_OPTIONS? > nor really understood the reason for these foo_MOUNT_OPTIONS... same > for the -nfs etc. command line flags. Make update fs-specific mount options in local.config file more easily when switching filesysm type to test? You don't have to update MOUNT_OPTIONS and TEST_FS_MOUNT_OPTS. The '-nfs'/'-9p' command line flags are used to indicate which filesystem it's testing and set FSTYP variable correctly. Because these filesystems can't be detected from $TEST_DEV automatically like XFS, ext4 etc. Thanks, Eryu -- To unsubscribe from this list: send the line "unsubscribe fstests" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
