Package: debhelper
Version: 7.3.15
Severity: minor
I have override rules that need to know whether they're being called from a
binary-arch vs. binary-indep target, viz:
override_dh_fixperms:
dh_fixperms
ifeq (,$(findstring -i, $(DH_INTERNAL_OPTIONS)))
chgrp shadow $(d)/libpam-modules/sbin/unix_chkpwd
chmod 02755 $(d)/libpam-modules/sbin/unix_chkpwd
endif
These commands must always be run when dh_fixperms is called for binary-arch
or binary, and must never be run when dh_fixperms is called for binary-indep,
since in that case the file won't exist and the commands will error out. I
/could/ check for file's existence instead, but I think that's an
unsatisfactory proxy; if something changes that causes this file to not be
there when it's expected (say, it moves around in the filesystem or moves to
a different package), this command should error out instead of being silently
discarded.
So the only way I can achieve this robustness is by checking the
DH_INTERNAL_OPTIONS env variable, but that's undocumented AFAICS. It would
be good to have a documented interface for querying the -a/-i options that
override rules can rely on.

Ah - yes, this is a much better option. Sorry for missing this.
