I'm not sure I follow ... I'm not a UNIX system administration expert,
but I am pretty sure the bash.bashrc file pertains only to bash. And
the current base version of that file only sets one variable: PS1. So
that's why I'm proposing the one-line patch.
I'm not sure why one would need to alter /etc/profile to create an
/etc/profile.d script, but I'm open to hearing more.
Of the various shells referenced in the provided /etc/profile, only
bash executes a custom file (in addition to executing the files in
/etc/profile.d), and it executes /etc/bash.bashrc.
I suppose an alternative, equivalent change to the one I originally
proposed might be to execute /etc/bash.bashrc *before* executing the
files in /etc/profile.d; either makes sense to me. I'm not sure what
the precedence order of those ought to be but my view is bash.bashrc
ought to be executed first as it is providing out-of-the-box defaults
and /etc/profile.d is intended for local modification.
I'd be willing to generate either patch. :)
