Hi James :)
you found a long-standing bug in ext2fs. Fixing it allows us to get
rid of the ugly workaround in daemons/runsystem.sh (look for `XXX').

So I guess we need to inhibit the RPCs here, not before calling
diskfs_reload_global_state, then do:
get_hypermetadata ();
map_hypermetadata ();
And reenable them here.
return 0;
}
I guess that means changing the diskfs API. James, do you want to
give it a shot?
In the mean time, enjoy my hacky workaround:
