IMO it's more important that we follow the Linux Standard Base spec than the release schedules of any specific tool(s) or even the kernel.

AGREED. As a "distribution neutral" certification, LPI will need to thread very closely along the lines of LSB. Any specific preferences for deviation must be kept at a minimal.
Dear Roy:
LPI has always been committed to the LSB. I'm not sure why everybody stresses this again and again in this thread. (Maybe we should add LSB-references to our objectives?)
The LSB will be no help with our task to create skill profiles for Linux systems administrators, though.
Let me explain:
The LSB [1] specifies programming interfaces and an execution environment to allow development and deployment of applications on any Linux distribution. It often refers [2] to ISO/IEC 9945:2003 [3].
The LPI defines skill profiles for Linux systems administrators based on common systems administration tasks. Whenever these tasks touch an area, which is covered by LSB, LPI refers to it. _But_ some tasks involve the _use_ of applications (firewall, mta, file server, ...). Don't forget that a systems administrator is mostly a user, not a Linux system programmer.
Going back to the initial question triggering this discussion--Bash 3:
Fortunately Bash is sh-compatible and thus it is one of the few killer applications which are covered in ISO/IEC 9945:2003. With its ample features, our main task is to extract an appropriate subset of the features [4]--not to desperately look for new ones. :-)
But even the LSB had exceptions from ISO/IEC 9945:2003's shell behaviour [5]. Therefore we should keep the freedom to explicitly add something, if LPI's surveys yield a common bash feature, about which Linux systems administrators should know to work efficiently. But I guess that corresponds to your wish that "Any specific preferences for deviation must be kept at a minimal", right?
