I'm using rsyslog 8.24 on debian. Each time I trigger logger "some message" the syslog refers to the same and only system user - it does not matter if I switch user (even as root), the messages are always logged as the same user - even on servers - I guess on a desktop, it's because the GUI is running as that user and on a server because I logged in as that user and later switch to root - could that be? But anyway, how could I log a message as root to the syslog?

Because logger uses getlogin(3).
https://github.com/karelzak/util-linux/blob/master/misc-utils/logger.c#L379
static char const *xgetlogin(void)
char const *cp;
struct passwd *pw;
if (!(cp = getlogin())
Which returns "name of the user logged in on the controlling terminal of the process". i.e. your system user.
