Hi,

Would it be possible to extend autoconf to allow ranges instead of just
one number for wired down devices. For example:


scsibus4 at umass0
sd8 at scsibus4

may become:


scsibus[4-5] at umass[0-1]
sd[8-9] at scsibus[4-5]

Is it good idea (if it cannot already be done)? Is this feasible and
what changes would be needed?
