rpm postun scriptlet leaks exit code to rpm

We use the following postun scriptlet:

if [ $1 -ge 1 ]; then

  if [ -x %{_sysconfdir}/init.d/mysql ] ; then

    # only restart the server if it was alredy running

    %{_sysconfdir}/init.d/mysql status > /dev/null 2>&1 && \

    %{_sysconfdir}/init.d/mysql restart

  fi

fi

The problem is that A && B construct, while it only runs B if A succeeds, it also sets the exit code to that of A, if A fails.

That is, if mysql status fails, the scriptlet exists with a non-zero code, and rpm treats it as a failure.

Possible fix: use if A; then B; fi instead of A && B.
