Sharing NFS file system (making it read only)

["Dvir Oren" <dviro@hotpop.com>]

I want to share the same file system for all of my etherboot clients. 
 I realize that some parts have to be different, and I intend to create 
ramdisks for them, and mount them.

However, if I make the NFS file system read only, I come across a 
lot of problems:

1.  I need /dev to be rw.
2.  I can't have /etc/passwd (and the related files) read only, if I 
want to add users, etc.  I can't have them link to somewhere else, 
passwd claims that it can't lock them.

Has anybody succeeded in making the file system read only?  I'm 
finding it extremely difficult.

Hopefully this isn't entirely off topic.
