[erlang-questions] Dialyzer HOME quirk

[Viacheslav V. Kovalev]

Hi folks.

When working with dialyzer on windows I've noticed some strange (for
me) behaviour. To find default PLT location dialyzer peeks into the
HOME environment variable, which is... hm... *not always* defined on
windows: https://github.com/erlang/otp/blob/maint/lib/dialyzer/src/dialyzer_plt.erl#L230

Erlexec, for example, knows about this fact:
https://github.com/erlang/otp/blob/41f2a54d9fed232be06a3c4be06779e9455a62b4/erts/etc/common/erlexec.c#L1523

I believe correct way to locate HOME is to use
`init:get_argument(home)`. Does anybody know any reason not to do so?
Why dialyzer use os:getenv("HOME") though?
