Correction to nanoBSD HOWTO page

[Philip Yarra]

I think there is an error on this page: 
http://www.freebsd.org/doc/en/articles/nanobsd/article.html

Specifically, this text:

===========================
A more useful example of a customization function is the following, 
which changes the default size of the /etc directory from 5MB to 30MB:

cust_etc_size () (
     cd ${NANO_WORLDDIR}/conf
     echo 30000 > default/etc/md_size
)
customize_cmd cust_etc_size
===========================

which suggests that putting 30000 in md_size will give a 30M /etc. 
Speaking for my own nanoBSD installations, to get a 50M memory disk, I 
need to put 50*2*1024 in md_size - I assume the allocation unit is 512 
byte blocks, but I'm happy to be corrected.

Regards, Philip.
