Description of problem:
as per
http://www.redhat.com/support/manuals/RHL-7-Manual/ref-guide/s1-kickstart2-commands.html,
--asprimary option for part command must be used with a numeric argument:
--asprimary <N>

            Forces auto allocation as a primary partition <N> or fail. <N>
can be 1 through 4. 

the anaconda kickstart.py code doesn't support that.  as per the code,
asprimary should not have any arguments.  the install fails with an error
message.

How reproducible:
Always

Steps to Reproduce:
1.  add lines to kickstart config file like
part /  --size 1024 --asprimary
2.   start kickstart install
3.   watch it fail
	

Actual Results:  install fails with an error:

partition command requires one anonymous argument

Expected Results:  partition created as a primary partition

Additional info:

this may also affect 7.1, didn't check.

also confused about --onprimary and --asprimary options.  i tried them in
every possible combination and permutation, and every time the
autopartitioning failed with the following error:
	Failed to allocate '/': no free primary
and so on, and switches to disk druid.  i am familiar with the trick to
specify a /boot partition to make sure that kickstart makes it a primary
partition.  but the other options that are supposed to specify whether the
partition is primary or not, don't work.
am i not using them correctly?

thanks
