I went ahead and run the attached script niced over the lintian lab
on lintian.d.o, which should cover all binary packages (amd64 + all)
from sid and experimental, the results are as follows:
.deb w/ data.tar.gz 20243
.deb w/ data.tar.xz 24425
.deb w/ data.tar.bz2 247
---------------------- -----
.deb total 44915
(The raw output can be found on my home dir on the lintian.d.o host,
I'll remove it in some weeks though.)
The number of source packages that produce all .deb w/ data.tar.bz2 is
81 (dd-list attached), which seems pretty low to me. So given this, and
if there's no compelling reasons to keep using bzip2, I think I'll just
go ahead and start the deprecation process by making «dpkg-deb -b»
issue a warning in 1.17.7 or .8, and filing a bug report to lintian.
Thanks,
Guillem
