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

This is a Wheezy system, running with sysvinit.
'man init' says:
ENVIRONMENT
Init sets the following environment variables for all its
children:
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.
