Previously posted: https://www.redhat.com/archives/libguestfs/2017-October/msg00032.html This takes a completely different approach. It turns out that POSIX / the shell already defines a special exit code 127 for ‘command not found’. We can make a small adjustment to lib/command.c to return this exit code in that case. Then we just have to modify the db_dump code to test for this exit code. I

I think I might be mad to include that many mailing lists in this patchset... As I explained in [PATCH 1/5], fstests covers more and more fs testing thing, so we always get help from fs specific mailing list, due to they learn about their features and bugs more. Besides that, some folks help to review patches (relevant with them) more often. So I'd like to bring in the similar way of

If running the external command fails in "argv mode" (ie. when not using the shell), then exit with either 126 or 127 as defined by POSIX. This is mostly the same as what bash does, see execute_cmd.c:shell_execve in the bash sources. Note: saving errno around perror(3) if necessary, otherwise you will see different behaviour between verbose and non-verbose mode. In non-verbose mode, perror(3) tried to print to a closed file descriptor, failing and overwriting errno. That took some time to...
