It seems recent versions of the lvcreate command support the %FREE flag 
when specifying volume size by extent.  If there were a way to 
configure autoinstallscript.conf to define the lv size by extent rather 
than only by the raw size, we could pass 100%FREE:

i.e.  <lv name="LogVol01" extents="100%FREE" />

This would generate the following lvcreate command:

lvcreate  -l100%FREE -n LogVol01 VolGroup00 || shellout
