Does POSIX compliance have to be the default mode, though?

It's sure useful to be able to have a POSIX environment available, but
it's more important that legacy scripts work out of the box.

It's my opinion that the POSIX environment should be opt-in, just like
/usr/xpg4/bin is still the Solaris 9 method of obtaining standards compliant
behaviour over legacy behaviour.  My preference would be to have a /usr/posix
for utility variants which conflict with the age old BSD behaviour.

This mechanism would also serve to replace the EXPR_COMPAT stuff - I'd
_really_ be miffed if release 5.0 of my preferred OS becomes the first OS
release to break a huge number of the scripts I've written over the past
two decades (I apologise for being way overdue in coming up with a migration
proposal for that one...).

Standards are good.  A working system is better.

		Cheers,

		Mark.
