Getting rid of /boot

[Roger]

And I was just about to ask what exactly is broken downstream... :-)
I've been driving several Fedora versions on several machines for several
>>> years now with a custom-partitioned disks (simple setups, typically just
>>> swap, / and /home, no LVM or anything such), and nothing "downstream"
>>> seemed broken, ever.

Question: with /boot / and /home partitions, do  /usr /etc /var and 
others all go into directories in /
I've never found out how the partitioning and install systems handle this.
