+Subject: [PATCH] test_syscalls: Do not print strerror(0)
+
+test_open_acc() prints strerror() of the expected error, which is 0 for
+the cases that should succeed. glibc returns "Success" for it, but musl
+returns "No error information", and run-tests.py treats the word "error"
+in the output as a failure:
+
+ FAIL examples/passthrough-base suspicious output: script.out: ... 49 [open_acc(O_RDONLY) mode: 0600 message: 'No error information'] START
+
+Print "Success" when no error is expected.
+

libfuse 3.18.3 replaced its pytest based tests with shell test cases driven by test/run-tests.py, so the pytest based run-ptest collected no tests at all. - Run test/run-tests.py from run-ptest and turn its result lines into ptest PASS/FAIL/SKIP lines. Use a run directory under the canonical /tmp, since some test filesystems mirror the real tree and cannot follow the /var/tmp symlink. - Install fuse_config.h, which the runner reads from the build tree. - Replace the pytest dependencies with the python3 modules the runner uses, and add coreutils and util-linux-losetup for dd status=none and losetup --show, which busybox does not support. - Do not print strerror(0) in test_syscalls, musl's "No error information" is flagged as suspicious output by the runner. All 87 tests now run on qemux86-64 musl: 80 pass, 7 skip.
