Enable postinst logging by checking the configuration in /etc/
default/postinst.

In this way, the postinst logging is enabled if 'debug-tweaks' is
in IMAGE_FEATURES, and at the same time, we avoid unnecessary rebuild
if IMAGE_FEATURES is changed.

This will over write the results of a previous postinstall because this is running in a for look, you should use >> instead of >.

I also suggested that the log file be a variable and you should use the ${localestatedir} as the base for /var. So you would add something like POSTINST_LOGFILE.

Thanks
