Managed to work this out by reading sysinstall code.  It is quite 
simple, but not so obvious from the manual page.  There appears to be 
two methods of selecting which dists to install:

1. Setting the distributions "by name" using something like:

 dists=base lib32 GENERIC SMP

The kernels have now been separated from "base", into their own dist, 
but you don't specify "dists=base kernels", instead you have to specify 
the subdistribution names.  Each of the dists values are looked up and 
the appropriate bit set for the variables below.

2. Setting the distributions by setting several bit field environment 


The above variables are bit fields as per sysinstall/dist.h, but must be 
converted to decimal because they are read using atoi(3).

Both methods work fine, but you can't select "all" within 
subdistribution using method 1 without putting every subdistribution 
name in (eg. for src - sbase scontrib scrypt ...), where as in method 2 
you can just turn all bits on (eg. 0xFFFFF, but in decimal). 

Best to refer to dist.h.
