BRLTTY cannot write to /var/log as it is running under an unprivileged user.
You need to put the log file to /tmp/ or some other directory where the
`brltty` user has write permissions.

Your original problem, by the way, most likely is that BRLTTY does not have
access to /dev/tty0. It is a permissions problem.

As far as I understand, Arch has not changed anyghing, it is Linux kernel
itself that has changed default permissions of /dev/tty devices.

You can try running your Arch with linux-lts kernel package to try to confirm
my theory.

There is a fix already in BRLTTY's git repository. It fixes this.
