+# At present, the RPC daemon works on Linux but not on OSX, because the current daemon
+# protocol runs over SOCK_SEQPACKET sockets, which Apple doesn't support.  In the long run
+# this will be a non-issue, as we expect to reimplement the daemon protocol using a secure
+# channel which will almost certainly run over SOCK_STREAM instead of SOCK_SEQPACKET.
+#
+# But this is all moot, because the HSM code to support use of multiple FPGA cores in
+# parallel doesn't quite work properly yet, so the daemon doesn't really buy us anything
+# useful, and just adds a bit of extra complexity to setup on Linux.
+#
+# So, for the moment, the default LIBHAL_TARGET is "serial" on all platforms.  If for some
+# reason you want to try out the daemon on Linux, just change this to "daemon".
