SIG-prefixed signals for `kill` are not POSIX compliant, so on Ubuntu CI (which defaults to dash instead of bash) the TEST-52 contains following error: [ 9693.549638] sh[51]: + systemctl poweroff --no-block [ 9693.553130] systemd-logind[26]: System is powering down. [ 9693.608911] sh[54]: /bin/sh: 1: kill: Illegal option -S This can be reproduced manually as well, either by running dash, or bash in POSIX mode: $ dash -c 'kill -SIGKILL 123' dash: 1: kill: Illegal option -S $ bash --posix -c 'kill -SIGKILL 123' bash: line 0: kill: SIGKILL: invalid signal specification
