Re: Updating isc-dhcp udeb to dynamically link bind (was: Bug#762762: nmu fixing bind issues)

If parallel building worked before you changed things, you get to fix
the issues rather than working around them. bind9 is a pain to build,
so having to deal with a forced -j1 is a nasty regression.

This udeb doesn't make any sense to me.

$ cat ./debian/libbind-export-udeb/DEBIAN/shlibs
libdns-export 100 libbind-export-udeb
libirs-export 91 libbind-export-udeb
libisc-export 95 libbind-export-udeb
libisccfg-export 90 libbind-export-udeb

The udeb is unversioned. ABI is going to be broken as usual in later
uploads, meaning the udeb shipping these shared objects will break
reverse dependencies:
  /usr/lib/libdns-export.so.100 -> libdns-export.so.100.2.2
  /usr/lib/libisccfg-export.so.90 -> libisccfg-export.so.90.1.0
  /usr/lib/libirs-export.so.91 -> libirs-export.so.91.0.0
  /usr/lib/libisc-export.so.95 -> libisc-export.so.95.5.0

I really fail to see how you could possibly imagine anything could work.

Since we're late in the D-I release cycle, since we're late in the
release cycle in general (window for transitions closed past month),
since there was no coordination whatsoever, and since there is
apparently no well thought through plan, I think I'll oppose isc-dhcp's
using such a udeb.

debian-release@ in Cc: to let the team now I might just block the bind9
package to make sure this udeb never reaches testing.
