          rstyxd - Styx-based remote execution and file service

          auxi/rstyxd alg ...

          Rstyxd provides a remote-execution service.  Having autho-
          rised the client and optionally established ssl, as
          described above, it reads a single line from its standard
          input.  The line contains a decimal value that is the count
          of the number of bytes that follow, which rstyxd reads as a
          utf(6)-encoded string.  The string contains a command, which
          is parsed into arguments, following the quoting conventions
          of sh(1). The first argument is the command name.  Rstyxd
          prepares a modified name space in which to run the command.
          It mounts the connection (standard input) on /n/client,
          binds /n/client/dev onto /dev, and opens the new /dev/cons
          (ie, the remote client's /dev/cons) on file descriptors 0, 1
          and 2.  Finally, it executes the command.

          Rstyxd is normally started by svc(8) in response to incoming
          network calls.  It expects the standard input to be con-
          nected to the client; unusually, it is both read and writ-
          ten.  It first authenticates the incoming call using
          keyring-auth(2) via security-auth(2). On successful authori-
          sation, the server sets its user identity to that of the
          caller, and the client can request that a digest and/or
          encryption algorithm be applied using ssl(3) to protect the
          data exchanged with the server.  Each alg names a digest or
          encryption algorithm that the server will allow the client
          to use, in any form accepted by ssl; the special name none
          is usually listed, to allow the client to choose not to use
