Startupscript and tmpfs

Hello maintainers,

there’s a little special problem, when using tmpfs for the /var/log.
Because OH won’t start if the log directory doesn’t exists at boot time.

Here is a little line, you could please add in file
/usr/share/openhab/bin/setpermissions.sh

for ohdir in "${OPENHAB_LOG_DIR}" "${OPENHAB_CONFIGURATIONS_DIR}"; do [ -d "${ohdir}" ] || mkdir "${ohdir}" setPermRecursive "${ohdir}" done

Many thanks for this … I am using now on a RaspberryPi where I moved /var/log to tmpfs.
However, I do wonder if reconfiguring logback.xml might be better? Or would both/either be wiped during an upgrade?
