With older util-linux(e.g. v2.17.2), running some tests(e.g. generic/472, generic/495) got the following output: ------------------------------------------------------- +mkswap: /mnt/xfstests/scratch/swap: warning: don't erase bootbits sectors + on whole disk. Use -f to force. +mkswap: unable to relabel /mnt/xfstests/scratch/swap to system_u:object_r:swapfile_t:s0: Operation not supported ------------------------------------------------------- 1) Before commit c1f1b30 of util-linux, standard mkswap didn't zap bootbits sectors and printed a warning until force option(i.e. -f) was given. We define "mkswap -f" as MKSWAP_PROG and replace all standard mkswap with $MKSWAP_PROG. 2) With mounting default SELinux context(e.g. system_u:object_r:root_t:s0), standard mkswap tried to reset the type of default context to swapfile_t if it is not swapfile_t, and then it failed and returned ENOTSUP expectedly as we don't want to create any SELinux attr on purpose. standard mkswap ignored this relabel error by commit d97dc0e of util-linux, but it still reported the error before commit d97dc0e. We try to skip the reset step in standard mkswap by mounting swapfile context directly. Note: We just mount swapfile context in related tests, and keep default context in the rest of tests.
