[systemd-devel] pid file /var/run/dhcpd.pid currenty exists

[XYZDragon]

Hello,

When trying to restart isc-dhcp-server, I was wondering why it didn't 
start. After executing the suggested `journalctl -xe` I could see that 
something was wrong:

May 27 13:32:15 my-pc isc-dhcp-server[26032]: Starting ISC DHCPv4 
server: dhcpddhcpd service already running (pid file /var/run/dhcpd.pid 
currenty exists) ... failed!

The message was helpful. I checked the file and noticed that it seemed 
contain a process id. After checking with `ps -p` it seemed that that 
process wasn't running anymore. In my opinion isc-dhcp-server should do 
this check itself without user interaction, deleting the file if it 
exists, but contains a process id of a dead process. After deleting the 
file everything worked.

Also note the word doubling 'dhcpdhcpd' and the missing 'l' in 
'currenty' in the debug message. Those could be fixed.
