Expected behaviour:

No such logs from lighttpd in /var/log/daemon.log.

Actual behaviour:

$ grep lighttpd /var/log/daemon.log
Jan  1 16:47:08 PiHole lighttpd[553]: grep: blacklist.txt: No such file or directory
Jan  1 16:47:08 PiHole lighttpd[553]: grep: blacklist.txt: No such file or directory
Jan  1 16:47:10 PiHole lighttpd[553]: grep: blacklist.txt: No such file or directory
Jan  1 16:47:12 PiHole lighttpd[553]: grep: blacklist.txt: No such file or directory
Jan  1 18:03:32 PiHole lighttpd[553]: grep: blacklist.txt: No such file or directory
Jan  1 18:03:43 PiHole lighttpd[553]: grep: blacklist.txt: No such file or directory
Jan  1 18:03:57 PiHole lighttpd[553]: grep: blacklist.txt: No such file or directory
Jan  2 23:51:16 PiHole lighttpd[553]: grep: blacklist.txt: No such file or directory
Jan  3 11:42:35 PiHole lighttpd[553]: grep: blacklist.txt: No such file or directory
Jan  3 11:42:35 PiHole lighttpd[553]: grep: blacklist.txt: No such file or directory

Since I use logcheck https://packages.debian.org/sid/logcheck to watch my logs I get emails for each such log.

Steps to reproduce:

Install PiHole and watch /var/log/daemon.log file. I am using PiHole on Debian stable.

Debug token provided by uploading pihole -d log:

Troubleshooting undertaken, and/or other relevant information:

I have not yet fixed it. I propose 2 options:

• check the file blacklist.txt exists before using grep(1) on it
  or
• provide an empty blacklist.txt file by default.

I will create an empty /etc/pihole/blacklist.txt file for now.
