The 'd' man page specifically refers to ".d.conf in the user's home directory", as opposed to "~/.d.conf"; I think those two definitions are allowed to diverge, from what I quoted above. The spec is unclear: how can you initialise HOME from "the user's home directory", if whatever the user's home directory is is only defined in
terms of the contents of $HOME, without reference to field #6 in /etc/passwd? That would be a circular reference to uninitialised data, that would!
Well, if it wasn't valid then there would be no sense to even set
$HOME, right? Because it would have always point to the same path as
the entry in /etc/passwd.
Anyway, I'm not doing this for fun but because my home directory is on
a removable drive and all applications I know honor $HOME (except
irssi where I had to alias irssi='irssi --home=~ --
