Arch Linux

My up-to-date Arch Linux installation on Amazon EC2 has vsftpd installed. It worked for a while until a recent kernel upgrade - sorry I cannot remember the exact version number.

Now when I attempt to start vsftpd from systemctl, the following errors appear in syslog:

Jan 21 11:38:40 ip-172-31-12-16 systemd[1]: Starting vsftpd daemon...
