The syntax overview no longer describes a line-based format, since that is not what the rest of the documentation shows. It now covers the grammar, the two naming conventions, the nine aliases, and the leading '-' on a path, and it says plainly that both formats are still read and told apart per file by content. Without that, a reader with an existing configuration is left wondering what happened to it. service-opts.md was a list of modifiers to place between a directive and its command, so it needed rewriting rather than translating: there are no positions left to describe. It is now grouped by what the settings do. conditions.md needed correcting. It presented '!' as a condition prefix alongside '~'. It is neither a condition nor a negation, it is a flag on the block that means one thing on a service and another on a run or task, so it is spelled reload-signal and required here, and the page maps the old form to both. Two things the pages claimed are not true. The kill delay range is 1-300, not 1-60, and stop and reload scripts are no longer run without a timeout. ChangeLog.md keeps its line-based examples. Those sit in historical release entries, and rewriting them in a syntax that did not exist at the time would misdate the format. Signed-off-by: Joachim Wiberg <troglobit@gmail.com>

Environment Variables
In Finit v4.3 support for setting environment variables in finit.conf,
and any *.conf, was added. It is worth noting that these are global
and shared with all services -- the only way to have a service-local
environment is detailed in Services Environment.
Global environment variables go in an environment block, env for
short:
environment {
foo = "bar"
baz = "qux"
}
On reload of .conf files, all tracked environment variables are cleared
so if foo is removed from finit.conf, or any finit.d/*.conf
file, it will no longer be used by Finit or any new (!) started
run/tasks or services. The environment of already started processes can
not be changed.
The only variables reset to sane defaults on .conf reload are:
PATH=_PATH_STDPATH
SHELL=_PATH_BSHELL
LOGNAME=root
USER=root
It is entirely possible to override these as well from the .conf files,
but be careful. Changing SHELL changes the behavior of system() and a
lot of other commands as well.
