#5 Ownership problem *.deb ==> *.rpm

[Vincenzo Zocca]

We analyzed an issue with alien 8.95-3.el7 on RHEL regarding file ownership. When converting from *.deb to *.rpm the file ownership changes to root. Adding one line print OUT "%defattr(-, -, -, -)\n"; to Rpm.pm resolved the problem we faced.

In attached file alien-deb-2-rpm-bug-ownership.zip the original Rpm.pm, the patched one and the patch are contained.
