Hi,

sorry for my ternseness. I'm not angry, I'm trying to solve the problem in the
best way, same as you. But I think we reached a point where the situation is
clear, everything has been articulated clearly, and the differences stem only
from different priorities, not misunderstanding. I understand that for you
keeping current cryptsetup-compatible setups functional is more important, but
for me sensible and consistent systemd behaviour is more important. More words
will not help the issue.

I read the man page (on Fedora, I'm not sure if it is the same) and while it's
true that it talks about "passphrase processing", it also does not explictly
say that hash will be ignored for a file. That section even talks about hashing
input read from stdin, and also about reading stuff from a file. So even if
cryptsetup ignores --hash when reading from a key file, it seems to be more by
mistake then by design, at least when judging by the man page.

As discussed on the ml, we'll keep current behaviour.
