I did another rebuild. Thanks to the Debian GNU/kFreeBSD cabal, the
results are available on io.debian.net. If you want shell access, read
http://io.debian.net/ssh.html . If web access is enough, go to
failed-packages.txt: list of packages that failed in one or the
other chroot, or which failed in both, but for a different reason.
failed-packages.dd-list.txt: same, dd-list sorted.
different-packages.txt: packages that generated different binary
packages, using debcmp.
different-packages.dd-list.txt: same, dd-list sorted.
logs.*/: build logs
pkg.*/: the generated packages
debcmp/: the output from debcmp
debcmp is an home-made script I use to compare packages, looking more
deeply than what debdiff does. It's available from
http://svn.debian.org/wsvn/collab-qa/tools/debcmp/ , if you want to
double-check the results.
My plan is to start filing bugs on the packages that failed to build,
and on those that differ in important ways (less/more files, less/more
Depends). It's already a lot of work. Is someone interested in helping
me with those tasks? Or maybe someone has an NM, and doesn't know what
he should do for T&S? ;)
In the meantime, don't hesitate to fix your packages!
