This test checks whether 'root' is successfully translated to UID/GID 0, using 'getpwnam' in libmount. This doesn't work in the chroot because /etc/passwd doesn't contain an entry for 'root' so skip it. The second test requires that '/sys/dev/block' is present, which is not the case inside the build container. --- util-linux-2.25.2/tests/ts/libmount/optstr 2015-01-23 13:58:41.181151194 +0100 +++ util-linux-2.25.2/tests/ts/libmount/optstr 2015-01-23 13:58:42.829161716 +0100 @@ -108,10 +108,6 @@ ts_run $TESTPROG --apply --user "noexec,nosuid,loop=/dev/looop0" 0x408 &> $TS_OUTPUT ts_finalize_subtest -ts_init_subtest "fix" -ts_run $TESTPROG --fix "uid=root,gid=root" &> $TS_OUTPUT -ts_finalize_subtest - ts_init_subtest "deduplicate" ts_run $TESTPROG --dedup bbb,ccc,AAA,xxx,AAA=a,AAA=bbb,ddd,AAA=ccc,fff=eee AAA &> $TS_OUTPUT ts_finalize_subtest --- a/tests/ts/lsblk/lsblk 2019-03-11 21:08:23.734387391 +0100 +++ b/tests/ts/lsblk/lsblk 2019-03-11 21:12:43.635473111 +0100 @@ -22,6 +22,8 @@ ts_init "$*" +ts_skip "/sys/dev/block is not available" + ts_check_test_command "$TS_CMD_LSBLK" ts_check_prog xz ts_check_prog tar
