[arch-general] Daemon No Longer Writes To Logs

always use less to view log files. vim makes a copy of the files you
open, and that could be a lot of unnecesseary IO for big log files.

When vim saves a file it actually saves a new copy of the file.
But postfix kept the old file opened and is still writing to it.

You can for example compare the inode of the file you see in the filesystem
ls -i /var/log/mail.log
and the node reported by "lsof -p <THE PID OF POSTFIX HERE>"
