Subject: [PATCH] Implement setfont --quiet
Current systemd-vconsole-setup implementation uses try and fail approach
while calling setfont. Starting with 1e15af4, it sometimes causes ugly
syslog messages:
/usr/bin/setfont failed with exit status 71.
setfont: ERROR kdfontop.c:183 put_font_kdfontop: Unable to load such font with such kernel version
Setting fonts failed with a "system error", ignoring.
It seems that systemd upstream already tried to address this problem, but
at that time they haven't found a good way.
The setfont --quiet is specifically intended for systemd-vconsole-setup,
and it will allow to suppress the error in systemd, but keep it in other
cases.
