Is that possible?  I looked at that briefly in the past, but ran into
problems because you need to be able to write some files (e.g., /etc/mtab)
before mounting additional filesystems.

I know the root filesystem is briefly mounted ro during boot, but I
thought it had to be remounted rw later.

Since this is a server I think (IMHO) that you need to be much more
careful about taking steps to prevent one service from interfering 
with any other.  It's especially critical to ensure that logs can't
be easily blocked by another process filling up the partition.
