I agree with Dan and yourself on this.  And I'm rather pleased to have
flushed it out, I could easily have used a LiveCD, but chose to go with
ubuntu since it's a very popular distribution (that I have to run in order
to support people).

The only advantage that a less feature-full shell like dash might give is
speed of execution, and given the application, this isn't a requirement for
automating builds, IMO.

It's always seemed a bit daft for the LFS book to build bash and then go to
a lot of trouble to make the bootscripts posix-conformant, I recollect
saying so when Nathan was struggling through it!

All the best,
