Re: [systemd-devel] nss-systemd
Indeed my systemd is version 245.4-4ubuntu3.15...
How could I know that the minimal required version was 249 (so I don't
bother you again!)?

Any suggestion?
Maybe your systemd version is simply too old? You need v249 at the
least for the above.

[systemd-devel] nss-systemd
Hello,
I'd like to dynamically provide group data when group data is queried by
the system (as in "getent group").
Since nsswitch can use systemd, I've looked at nss-systemd.
As a first step I tried to define a Static Drop-In JSON User Record
(because user definition is documented with more details than group
definition).
So I added a toto.user in /etc/userdb/ with this
{
"userName" : "toto",
"uid" :
}
and a .user file pointing to toto.user
But when I run "getent passwd", there's no toto user.
I tried to see a bit what's going on with strace and I see that getent
opens libnss_systemd.so.2 and looks for files in /run/systemd/userdb.
But it's not even trying to read in the directories |etc/userdb/|,
|/run/userdb/|, |/run/host/userdb/| and |/usr/lib/userdb/|

Any suggestion?
Sincerely
