Hi Joro,

if you really want to rename the plugin - that's ok. But I have
a few questions about the problem.

I assume that when the name "socket_peercred" was initially suggested,
things used to work. What has changed, so it doesn't load anymore?

As far as I remember semantics of system variables is as following:
if plugin variable conflicts with server variable, server variable
wins. Still plugin variable may be referenced as "--plugin-...".
If this rule still applies, do we agree that there is something
wrong and are we going to fix what went wrong?

More interesting, you say that "socket_peercred" conflicting with
"socket". But this way why "flush" is not conflicting with "flush_time",
"old" is not conflicting with "old_alter_table", "shared_memory" is
not conflicting with "shared_memory_base_name", etc?

Regards,
Sergey
