The migration guide covered a stanza at a time, which is the wrong
shape for the two idioms that repeated a whole stanza. One of them,
several candidate binaries for one service, is now a command list.
The other, one service gated differently per platform, has no block
equivalent: those blocks share an identity because they share the
barrier condition downstream services wait for, so they cannot be
given separate titles. For that one the guide says to split the
variants across files, or leave that file in the line-based format,
which Finit still reads.
The udevd example in services.md taught the merge-broken form, and
system/10-hotplug.conf.in pointed readers at it for their syslogd.
Also lists libConfuse among the build dependencies. It has been
mandatory since the new .conf format landed, and build.md still said
two libraries. And corrects the note on variable expansion: it is
${VAR} that libconfuse expands when the file is read, with
${VAR:-default} supported. A plain $VAR reaches the service, which is
what makes `command = "syslogd -F $SYSLOGD_ARGS"` work with envfile.

The new-format reference describes the block format on its own terms,
which is the wrong lookup direction for someone holding a legacy
one-liner. Aaron migrated Finix OS from the PR description, proving
the need for a token-in, key-out mapping in the user guide.
One table per part of a stanza, worked conversions for the shapes
that changed structurally -- cgroup selection and the three tty
variants -- and the dropped tokens listed with their replacements.
