Public bug reported:
When starting isc-dhcp-server, the following appears in syslog:
Apr 5 01:20:06 nibbler dhcpd: Can't create PID file /var/run/dhcpd.pid:
Permission denied.
Apr 5 01:20:06 nibbler kernel: [293336.249992] type=1400
audit(1333614006.094:47): apparmor="DENIED" operation="mknod" parent=1
profile="/usr/sbin/dhcpd" name="/run/dhcpd.pid" pid=12427 comm="dhcpd"
requested_mask="c" denied_mask="c" fsuid=107 ouid=107
Even when adding to dhcpd.conf:
pid-file-name "/var/run/dhcp-server/dhcpd.pid";
it produces:
Apr 5 01:33:39 nibbler kernel: [294149.878702] type=1400
audit(1333614819.902:48): apparmor="DENIED" operation="open" parent=1
profile="/usr/sbin/dhcpd" name="/run/dhcp-server/dhcpd.pid" pid=13392
comm="dhcpd" requested_mask="r" denied_mask="r" fsuid=107 ouid=107
due to not having read access in the AppArmor profile:
/{,var/}run/dhcp-server/dhcpd{,6}.pid w,
If this is truly where the pid should be, the compiled-in default should
be changed, as well as the AppArmor profile tweaked for read access.
