That was where I went initially, but I thought that means that the<br>
user now needs to configure aio-max-nr in two places, once in<br>
sysctl.conf and once in /etc/default/multipath-tools (for when
running<br>
multipath tools by hand or in scripts). I thought this solution<br>
resulted in less overall system configuration. The<br>
/etc/default/multipath-tools is more explicit, so it does have<br>
advantages too.<br>
