It's running fine with:

pi@pi1:~ $ sudo ls -l /var/log/snowflake
insgesamt 4
-rw------- 1 snowflake snowflake 3871 20. Nov 00:44 snowflake.log

I have put the installation steps into a tiny repository.

Just came across this and figured I'd explain in case someone else does too.

When you're using the systemd StandardOutput or StandardError directives, these streams are redirected by the systemd daemon itself, which is running as root, so the snowflake proxy service doesn't need write access to the log file. When you use the command line switch, it opens the log file itself, in which case it does need write access.
