The way I've been doing it for quite some time is to make /var a
separate partition, put the home directories on /var/home, and then
bind-mount /var/home on /home. In /etc/fstab that's:
/var/home /home none bind 0 0
To keep SELinux happy, you need to set up an equivalence of /var/home
semanage fcontext -a -e /home /var/home
It's all completely transparent in the running system. The only time I
have to remember that it's set up that way is when I'm looking in my
backups and need to know that home directories are backed up as part
