This post describes the stuff I did to my Raspberry Pi 2, which is the current acting home server. These configuration steps are probably useful for everyone.

/etc/network/interfaces- it makes configuring the network more complicated.
dphys-swapfileconfigure a swap file in the root partition - I have no idea why anyone wants that.
triggerhappynot entirely sure what it does, probably useless - I have never used it.
raspi-configmesses with your CPU frequency governor at boot, of course you want to use the
bluez*are the Bluetooth related things. I don't use Bluetooth.
/etc/rc.local, so your IP address doesn't come up in the boot screen - I found it weird.
/etc/sysfs.conf, these ensures that your CPU always runs at the fastest speed. You should be using zswap anyway.
