>From a Linux distribution perspective, there's also the question of if s6 can be
made a drop-in replacement for daemontools, since it does follow djb's naming
scheme. In gentoo, there are various packages that depend on
virtual/daemontools; for example, the nullmailer test suite uses ipcserver. From
a quick comparison of the documentation, it looks like s6 only adds options, and
remains compatible with the daemontools options.

So would it be valid/acceptable for a distribution to create unprefixed symlinks
to the s6-* binaries? It looks like this would mostly only work for the subset
of the binaries that implement daemontools functionality; some others
(s6-setsid, s6-sudo) would have naming conflicts if they were not prefixed.

Then, with the symlinks, s6 could "provide" virtual/daemontools. Maybe this
would also help discoverability (the issue at hand). Maybe the inconsistency
would cause more harm than good, and the symlinks should be "for compatibility
