The interactive editor does support percentages:
Quantities are rounded to the nearest cylinder when units are specified
for sizes (or offsets). At prompts that request a size, `*' may be
entered to indicate the rest of the available space, `%' for percentage
of total, and `&' for percentage free.
Default is to use the whole disk anyway. There is also a section
called AUTOMATIC DISK ALLOCATION that can use a templkate file.
