> If the root filesystem is mounted read-only, will pipes continue to work?

What variant of unix are you using?  Most SystemV-like unix's I have seen
allow the specification of a "pipedev" which is the filesystem that will be
used for pipe space (inodes and such).  The BSD systems I have seen use
the kernel socket routines to implement pipes.  I know of no Unix that
requires that the root file system be used for pipe space, althogh I'm sure
someone out there will enlighten me...
