You are correct.  The only time the "bin" directories are written is
during system updates.

I am not sure how much improvement you will see by putting the common
system commands in a ram disk.  The demand paging system keeps
frequently accessed pages in memory anyway. The only way to know is to
try it and see what kind of improvement you see.
