Add truncate: to StandardOutput= etc. This adds the ability to specify truncate:PATH for StandardOutput= and StandardError=, similar to the existing append:PATH. The code is mostly copied from the related append: code. Fixes #8983. 2021-01-15 00:32:55 +03:00			`[Unit]`

test: fix exec-standardoutput-truncate test The cmp in ExecStartPost= was actually failing – ExecStartPost= has the same StandardOutput as the rest of the service, so the output file is truncated before cmp can compare it with the expected output – but the test still passed because test_exec_standardoutput_truncate() calls test(), which only checks the main result, rather than test_service(), which checks the result of the whole service. Fix the test by merging the ExecStartPost= into the ExecStart= – the cmp has to be part of the same command line as the cat so that the file is not truncated between the two processes. 2021-01-15 22:01:44 +03:00			`ExecStart=sh -c 'cat && cmp /tmp/test-exec-standardoutput-output /tmp/test-exec-standardoutput-expected'`
