Six diagnostics and eight comments explained where an environment
variable comes from by naming the module file that sets it. The reader
of a panic is an operator, who does not edit that file; the reader of
the comment is already in the code. Neither can act on a filename, and
a filename in prose is checked by nothing.
Each one now names what the reader can act on: the option where there
is one (services.hyperhive.network.bridgeName, .bridgeIp,
.bridgePrefixLength, c0re.assets, c0re.orgAvatarPng), otherwise the
unit the process is expected to run under. Two of the six diagnostics
had a real option available; the other four have none, so they name
the unit rather than an invented path.
Four of them pointed at hive-c0re.nix, which is a directory. Two of
those spelled it nix/modules/hive-c0re.nix — a directory that does not
exist either, and one of the two was wrapped across a line break, so
no grep for the whole path could have found it. That is the argument
for the change: prose naming a file rots silently because nothing
compiles it.
Scope here is the four files around those diagnostics. The same
pattern still matches elsewhere in the tree; that sweep follows.
