Hyperbola with linux-libre-lts on OpenRC is similar to parabola. Boots into user account in command line in at around 100MB xorg adds another 20MB ontop to around 120MB. Booting into a user shell seems to be more memory expensive than starting as root.
I want to boot to command line in no more than 20MB with a GUI that brings me up to no more than 40-50MB of memory usage. Any more than that and there is too much going on.
