I for one don't consider that high praise, I'm not happy with packages
taking it upon themselves to edit /etc/nsswitch.conf. :)  By my reading,
that's a violation of Debian Policy ¶ 10.7.4, but one that's been quite low
on my list of bugs to file so long as PAM remained in disarray.

I agree with Loïc here that setting environment variables (via
/etc/profile.d or elsewhere) for the /user's/ benefit should not be
understood as prohibited; this is a prohibition on shipping programs that
depend on environment variables being set for correct operation, not a
prohibition on conditionally setting environment variables from within

At any rate, /etc/environment seems the more appropriate place to make this
change.  (I don't think /etc/environment.d makes sense - added complexity in
pam_env for precious little gain.)
