+Etcd is a distributed reliable key-value store for the most critical
+data of a distributed system, with a focus on being:
+    Simple: well-defined, user-facing API (gRPC)
+    Secure: automatic TLS with optional client cert authentication
+    Fast: benchmarked 10,000 writes/sec
+    Reliable: properly distributed using Raft
+
+Groupname and Username
+
+You must have the 'etcd' group and user to run this script,
+for example:
+
+  groupadd -g 355 etcd
+  useradd -d /var/lib/etcd -s /bin/sh -u 355 -g etcd etcd
+
+For some basic setup instructions, check the included 'README.SBo'.

+To start etcd automatically at system startup, add the following to

+
+  if [ -x /etc/rc.d/rc.etcd ]; then

+To stop etcd automatically at system shutdown, add the following to

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
