David Gibson ff2ff2fbca test: Make log truncation test more robust ... test/pasta_options/log_to_file checks that pasta truncates its log file when started. It does that by starting pasta with a log file once, then starting it again and checking that after the second round, the log file has only one line: the startup banner from the second invocation. However, this test will break if the second invocation logs any additional messages at startup. This can easily happen on a host with multiple network interfaces due to the "Multiple default route" informational messages added in 639fdf06e ("netlink: Fix selection of template interface"). I believe it could also happen on a host without IPv6 connectivity due to the "Couldn't pick external interface" messages, though I haven't confirmed this. Make the log file test more robust, by not testing for a single line, but instead explicitly testing for the PID of the second pasta invocation in the banner line.
