It is.  In any case, /usr is part of the / partition.  In case it
matters, /var is a separate partition.  And I'm using software raid 1
for both / and /var.

I will do this, but I can't reboot just yet to check it out.  I will
post my findings later.

This is a Wheezy system, running with sysvinit.  

'man init' says:

       Init sets the following environment variables for all its

       PATH   /bin:/usr/bin:/sbin:/usr/sbin

So maybe it's not a path issue after all.  What else could it be then?
The boot messages clearly indicate that it's failing to find
/bin/dirname and /bin/basename.

Thanks for your help.
