Well we don't even need a fixed dir, a session generated dir with an env variable set to it is enough.

Or we could put that somewhere else in var. We created /var/run/<users> dirs, there is no reason we couldn't do other directories for other uses.

I am pretty sure I have used some BSD in the past where the home directories were in /usr/home and /usr/local is a pretty good spot to put what is -- wait for it -- local to the machine!

There is no reason we couldn't have all our user owned binaries in /usr/local/<username>/bin and /usr/local/<username>/lib and our configs in /usr/local/<username>/etc

It would just have to be created at user creation with correct user rights but that is no big deal.

Users would just put their files in their /home, be able to sync it accross machines/ possibly different OSes without necessarily synchronising config files that do not apply to it or worse, unneeded cache files. Their /usr/local/<username>/etc could be a git (or other versionning system) repo Their /usr/local/<username>/bin lib share whatever could be saved and restored easily

And all the variable/ephemeral shit/cache could go to var where they belong.
