In both OSes I noted that `source´ built-in does not work on a FIFO. On
CentOS the command is just ignored, and on cygwin it blocks indefinitely (I
guess).  Ok, cygwin FIFOs may not be a good test case, but  I think CentOS
ones are.

This was changed about five years ago, before bash-4.0 was released.

Oh, sorry.

My CentOS 5 is still on bash-3.2.25. I must be quite unlucky, since on
3.2.48 it works.

That's interesting, since there are no bash-3.2 patches between 25 and 48
that touch that part of the code.  I wonder if the CentOS people folded
in other changes.

CentOS 6 promises to do better, but unfortunately it is not compatible with
CentOS 5.

Really?  How is it incompatible?  That's unusual for CentOS, from what I

I also think it is unusual, not to mention 'not nice' at all to their users !

But they say on the website you can not upgrade CentOS 5 to CentOS 6, even though the installation media does prompt the user with an 'upgrade any' option when the installation starts.

And I also hear there are many system utilities that work differently and have been changed ...

I do not really mind re-installing my machines, to get up-to-date, but I can not expect my company clients to do the same, so bad luck for me, I guess. :(
