Here is the proposed "official" MINIX file system layout as of 1.4b.
It is not entirely academic, because I was having a lot of trouble with
<minix/*.h>  etc.  Having two copies, one in /usr/include and one in 
../h became unmanageable.  They couldn't be links because I have them
on different disks.   I have added /usr/include/blocksize.h, which is
all that most programs wanted anyway, and changed the other programs like
ls and diskcheck to #include "/usr/src/fs/const.h".  There are only a few
such programs and they are all programs that have to know about the 
inner workings of the system.  Ordinary user programs are not affected.
