re-post - this time also reaching out to the full ubuntu-devel list so that
this could be decided before the impending FF next week.
*TL;DR:* is just dh/dh_auto_configure cross build safe enough these days to
allow liblockfile becoming a syncpackage in zesty?
- Yes a sync should be safe for zesty
- No, we still need the delta (adapted to new d/rules)
- No, we want to wait until it stabilized again in Debian and only
consider it in zesty+1 (I have never touched any of the reverse-depends to
this so it is hard for me to decide)
- about the changes in liblockfile:
- about the Ubuntu delta, see my older mail forwarded below

I asked on IRC before  but it might have been lost.
TL;DR: is just dh/dh_auto_configure cross build safe enough these days?
I need your advise and experience on general packaging and cross
compilation on that.
The old change is from you Adam, so I wanted to ask you.
Similar (to me) changes I've seen often are from Doko, so I set him on CC
for an extra pack of experience.
The package liblockfile was all-the-same for quite a while.
Recently there seems to be an influx of upstream and Debian packaging
Our only Delta is "Explicitly set CC with DEB_HOST_GNU_TYPE if we're
DEB_HOST_MULTIARCH ?= $(shell dpkg-architecture -qDEB_HOST_MULTIARCH)
+DEB_HOST_GNU_TYPE ?= $(shell dpkg-architecture -qDEB_HOST_GNU_TYPE)
+DEB_BUILD_GNU_TYPE ?= $(shell dpkg-architecture -qDEB_BUILD_GNU_TYPE)
+ export CC = $(DEB_HOST_GNU_TYPE)-gcc
+ INSTALL += --strip-program=$(DEB_HOST_GNU_TYPE)-strip
But the new d/rules dropped almost all and uses almost only dh defaults in
the more recent packaging:
dh_auto_configure -- --enable-shared --with-mailgroup
The older Delta is 5 years old since the package didn't change at all.
But the question that I can't answer alone is, if just dh/dh_auto_configure
would be cross build safe enough these days?
And if so if this shall just become a sync then, because that was the only
delta that is left
