fixes:
- Fixes an issue where the socat process would exit on client disconnect,
which would (a) leave a zombie socat process in the process table and (b)
disable any subsequent serial console connections. This issue was
addressed by updating ironic to call socat with the
``fork,max-children=1`` options, which makes socat persist and accept
multiple connections (but only one at a time).
