Hi all,
A recurrent theme in recent discussions of package maintenance has been keeping
track of when forked Devuan packages are out of date with respect to
Debian[1]. Hopefully to make this easier, I have just enabled the API to query
information from our instance of dak.
To make use of it:-
 - Install the devscripts package.
 
 - Configure the Devuan URL by adding
   "RMADISON_URL_MAP_DEVUAN=
https://api.pkginfo.devuan.org/madison" to
   ~/.devscripts
   
 - Use rmadison with '-u devuan' switch to query Devuan's packages.
Example:-
% rmadison xrdp
xrdp       | 0.6.1-2         | oldoldstable            | source, amd64, armel, armhf, i386
xrdp       | 0.9.1-9+deb9u3  | oldstable               | source, amd64, arm64, armel, armhf, i386, mips, mips64el, mipsel, ppc64el, s390x
xrdp       | 0.9.1-9+deb9u3  | oldstable-debug         | source
xrdp       | 0.9.8-2~bpo9+1  | stretch-backports       | source, amd64, arm64, armel, armhf, i386, mips, mips64el, mipsel, ppc64el, s390x
xrdp       | 0.9.8-2~bpo9+1  | stretch-backports-debug | source
xrdp       | 0.9.9-1+deb10u1 | stable                  | source, amd64, arm64, armel, armhf, i386, mips, mips64el, mipsel, ppc64el, s390x
xrdp       | 0.9.9-1+deb10u1 | stable-debug            | source
xrdp       | 0.9.12-1.1      | testing                 | source, amd64, arm64, armel, armhf, i386, mips64el, mipsel, ppc64el, s390x
xrdp       | 0.9.12-1.1      | unstable                | source, ppc64el, s390x
xrdp       | 0.9.12-1.1      | unstable-debug          | source
xrdp       | 0.9.15-1        | unstable                | source, amd64, arm64, armel, armhf, i386, mips64el, mipsel
xrdp       | 0.9.15-1        | unstable-debug          | source
% rmadison -u devuan xrdp
xrdp       | 0.9.12-1.1+devuan1 | unstable   | source, amd64, arm64, armel, armhf, i386, ppc64el
I will add this information to the Maintainers guide.
I will also try to get Devuan's rmadison url added to the Debian package so
manual configuration will no longer be necessary.
Best wishes
Mark
