Why do you need to use the actual FFS code?  If this is for a boot
program, use the FFS reading package in libsa.

You could certainly also add simple write support to the libsa FFS
package.  I mean, it's not like you have to interact with the buffer
cache, deal with the vnode layer, etc. in a boot block :-)
