That is very odd, I don't know why ash would work and sash does not.
Very strange indeed.

This sounds like you do not have proper /dev/* populated..  i.e.
/dev/console, /dev/tty, /dev/pts, etc.  For initial system bringup you
can ignore that warning.  (However, keep in mind that ctrl-C, ctrl-Z,
etc job control will not work..)  This might also partially be a symptom
of ash starting as process 1, process 1 contains special rules in the
kernel as it is the init process.
