rpm postun scriptlet leaks exit code to rpm
We use the following postun scriptlet:
1
2
3
4
5
6
7
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.
