What commands besides ln(C) do not work across filesystems?

As a relative newcomer to Unix (though I have administered
another type of network system for the last five years) and as
the sole person here capable of administering our new Xenix system,
I made an educated guess (based on the SCO 2.3.1 installation docs)
to follow their recommendation and create a separate /u
filesystem (page 2-6 to 2-7 of the XENIX Installation Guide).  I
liked the idea that I would likely gain speed, faster backups,
and better crash security... but I was unaware that some commands
(like ln(C)) do not work across filesystems.  While installing
Menushell recently, I tried to use their linkusers script to ln
some programs to various user's home directories, and of course I
was unable to do so.  I figure I can just create a /u/bin
directory and copy the commands I want to link there, which will
lose me some space and some standardization, but would be an
acceptable workaround, I guess.  

Can someone suggest a better one?

Also, what other problems am I going to run into with this
configuration that the installation manual didn't warn me about,
except in the most general of all possible senses?  What other
commonly used commands don't work across filesystems?

Would I be better off backing up everything and reinstalling now,
before the system begins to be heavily used?

And SCO, if you are listening, would you please include in your
installation notes a list of commands that do not work across
filesystems, so that other relative novices who have to make this
decision are a little better informed?  You've done a great job
with your revision of docs from 2.2 to 2.3, particularly in the
System Adminsisttator's Guide, and I appreciate it, but this one
thing, had I known it then, would likely have convinced me to
decide otherwise.

All responses appreciated.  If sufficient interest, I will post a
summary.
