* Property has been converted to a GADT, and will be Property NoInfo
or Property HasInfo.
This was done to make sure that ensureProperty is only used on
properties that do not have Info.
Transition guide:
- Change all "Property" to "Property NoInfo" or "Property WithInfo"
(The compiler can tell you if you got it wrong!)
- To construct a RevertableProperty, it is useful to use the new
(<!>) operator
- Constructing a list of properties can be problimatic, since
Property NoInto and Property WithInfo are different types and cannot
appear in the same list. To deal with this, "props" has been added,
and can built up a list of properties of different types,
using the same (&) and (!) operators that are used to build
up a host's properties.
Particularly, the Makefile would try to build propellor if there were
updates, but if this build failed because a bad commit was pushed, it would
abort w/o pulling any new fixed commits.
Anyway, it's better to move away from using the makefile when possible as
it's just for bootstrapping, and also I would like to make "make" not
default to running propellor as that can be confusing behavior.
(I can't change that yet; needed for upgrades. Should be fine to change
after several more releases, or maybe a year..)
This is to work around OSX's brain-damange regarding filename case
insensitivity.
Avoided moving config.hs, because it's a config file. Put in a symlink to
make build work.
