Manoj, the problem with this discussion, I think, is that you use the word
"essential" with two different meanings, namely:
1. That bash has the essential flag in the control file.
2. That bash is a very important package and we should never never never
let the user to remove it from their system under any circumstance even if
there is a posix /bin/sh replacement, not today nor tomorrow nor the year
2000 nor the year 2010.
and mix the two meanings constantly.
I am *always* talking about essentialness in the first meaning.
The fact that 90% of scripts *already* use /bin/sh and not /bin/bash
*proves* that bash is not as essential (in the *second* meaning) as you
say, and therefore making it non-essential (in the first meaning) is, at
least, something we should consider the day we have another /bin/sh other
