When ulogd is run by systemd on Debian, it logs messages to the journal,
it used a PID file in /run/ulog/ulogd.pid, and logs packets to
/var/log/ulog/syslogemu.log. This last ones triggers a dac_read_search
capability check because the directory is configured as:
drwxrwx---. ulog adm /var/log/ulog
(root does not have an access to the directory without bypassing the DAC.)
Add a comment describing how to avoid allowing dac_read_search to ulogd_t.

Debian uses /var/log/ulog/syslogemu.log by default to log network
packets sent through a netlink multicast group by the firewall.
