Phasing out forwarding of locale settings
<https://lists.mindrot.org/pipermail/openssh-unix-dev/2021-September/03958...
I think Fedora should do this unilaterally, dropping the downstream
additions that enable locale forwarding in both the default client and
server configurations. If we do that, the OpenSSH server will use the
locale as configured with localectl for new interactive and
non-interactive sessions, which is C.UTF-8 in many cases. At least
that's what my testing on Fedora 33 suggests.
Comments?
We have a big problem that nobody speaks about: MacOS.
The default and correct value of LC_CTYPE on MacOS is "UTF-8", but this is not a
valid Linux locale string. And MacOS sends this by default - so, given the popularity of
MacOS, the only sensible thing to do for Linux is not to accept locale-related environment
variables. Or at least, filter out known bad values somewhere, but that would be a lot of
fragile distribution-specific logic that I would rather not see.
