Are # lines stripped always, even in scriptlets?
No, because whatever is in scriptlets body belongs to the scriptlet
interpreter which certainly is not rpm. Oh, I know...
To that cause, I just submitted
https://github.com/rpm-software-management/rpm/pull/753. Doesn't help
with comments after %endif though.
Just FWIW, %dnl support is now in rawhide.
What it means in practise is that for the first time there's now a way
to escape macro expansion for the rest of the line (so eg multiline
macros such as %configure can be commented out with it), it's possible
to add comments to macros themselves and comments can appear anywhere in
the spec.
The classical example of this is comments intended for the scriptlet
below ending up in the previous scriptlet body.
---
%post -p /sbin/ldconfig
%dnl postun is needed to handle foo
%postun
%dnl always do bar first
%{_bindir}/do_bar
%{_bindir}/do_foo
---
...results in:
$ rpm -qp --scripts scriptintr-1.0-1.fc30.noarch.rpm
postinstall program: /sbin/ldconfig
postuninstall scriptlet (using /bin/sh):
/usr/bin/do_bar
/usr/bin/do_foo
...wheras #-comments would end up in the package and in case of "postun
is needed to handle foo", in the body of the wrong scriptlet that will
cause ldconfig to complain.
