[systemd-devel] Additional Locale Variables for Units and Number Format

Thank you, I think LC_NUMERIC will work for the number formatting, my company is also looking for something along the lines of this, and hoping to use locale/systemd to handle it:

It sounds like you're reinventing LC_NUMERIC.
The locale system has a lot more than just LANG; it already allows the
number format to be overridden separately from the "language". Take a look
at `locale -k LC_NUMERIC` and <
https://pubs.opengroup.org/onlinepubs/009695399/basedefs/xbd_chap07.html>.
Adding custom variables would require changing a lot ? I guess the main
consumers are libc (Glibc) and libstdc++ (GCC), but of course there are
many places which set the existing LC_* and expect things to change
accordingly, or which might implement the standard interfaces on their own
without using libc.

No, you can use systemd-cat to then invoke your script which applies
to every output of it.
Also, you can just use reply-all in gmail (or even set it as the
default in the settings) to have the correct behaviour of sending
mails also the the mailing list.

OK, I will dive into it.

I will do that then. Only problem is that the original poster will get the
message two times.
Except when I remove the To. But forgetting to remove that is not as bad as
not sending it to the mailing list.

FYI I implemented your design this afternoon in case you have some time
to review.

Hello again,
shelving that multiple BT adapters idea for a moment, since that doesn't
seem to be a supported configuration, more's the pity,
the issue with GNOME seems to be that /dev/rfkill doesn't get the right
permissions. It's tagged "uaccess" alright, the intention seems to be that
(active) logged-in users get rw-, but this only actually works on seat0. If
both seats idle at the greeter, gdm (or lightdm) gets rw- via ACL. If I
login at seat0, that ACL is replaced by an identical one for my user, and
the GNOME BT panel works. If I login at seat1 instead, nothing changes,
there's still just the one ACL for the greeter's user (and obviously the
GNOME BT panel is broken).
Obviously I could just override the regular permissions via udev rule, give
it to an "rfkill" group or something, but I'd rather do it properly.
Kind regards,
Christian Pernegger
I login on seat0, my user gets r
