Home, swap encryption, that/TMP run in memory

Use/dev/urandom, not/dev/random, because the/dev/random will start very slowly. (/dev/random must receive enough random factors to work, so it's slow and you have to press the keyboard when you start.) /dev/urandom is non-blocking, although security is a little bit close, but enough. ）
