Installing SunOS 4.1.1 on a Sun SPARCStation

I was recently given (don't ask how) a SUN SPARC and am in the process of reinstalling software on it.  I installed the miniroot system from tape and tried to run the
/usr/etc/install/ utilties, but the partition with the root system is mounted readonly.  I need to know how to mount the drive read-write.  My boot command is:
b /sbus/esp/sd@3,0:b vmunix (partition b of sd0, the default for the miniroot setup)
I could really use help on how to install SunOS.  Thanks.  (my benefactor bought manuals for sunview, but not SunOS)

Hello:

   What is happening is that your miniroot partition is monted in the swap are (partition  "b") and you can't do anything to mount it differently, nevertheless the only thing you need to do is to run the installation comand (it used to be suninstall) and the rest of the process should be straightforward if you know UNIX admin.

Maybe you have to change to the directory where the comand is, I think it used to be in /usr/etc/install but could be somewhere else.

After posting the question, I found a way to mount the root partition read-write.  Instead of using:
b /sbus/esp/sd@3,0:b vmunix
simply add a -rw to the end (for readwrite) making the final boot command:
b /sbus/esp/sd@3,0:b vmunix -rw
You should really run suninstall as suggested because disk space might be tight and I believe df (disk free) is not available on the miniroot system.
