[lttng-dev] checkinstall and lttng-ust with Java/JNI support

[Thibault, Daniel]

   I was fooling around with checkinstall in order to create installation packages for lttng-modules, userspace-rcu, etc., when I ran into what seems a very obscure bug (googling for the error message "unable to create `/proc/self/coredump_filter.dpkg-new'" brings up nothing).

   It occurs when building the Debian package for lttng-ust, but only if Java/JNI support was requested. That is to say, building lttng-ust with no extra support or with just systemtap support packages just fine.

   But when I build it with JNI/Java support, the 'sudo checkinstall make install' runs into this at the end:

Selecting previously unselected package lttng-ust-java.
(Reading database ... 147274 files and directories currently installed.)
Unpacking lttng-ust-java (from .../lttng-ust-java_2.2.0-rc1-12_amd64.deb) ...

   Note that the install supervised by checkinstall worked fine, and the package was built successfully: the problem occurs when the package is fed to apt, it seems.  The resulting package will cause the same error when run through the Ubuntu Software Centre, for instance, meaning it is unusable.

   Any clues as to what is failing here?
