+Q. Where did urpmi completion go?

+A. Guillaume Rousse <rousse@ccr.jussieu.fr> now maintains it separately as
+   part of the urpmi RPM package.
+
+Q. Why is rpm completion so slow with -q?
+
+A. Probably because the database is being queried every time and this uses a
+   lot of memory.

+   You can make this faster by pregenerating the list of installed packages on
+   the system. Make sure you have a readable file called /var/log/rpmpkgs.
+   It's generated by /etc/cron.daily/rpm on modern Red Hat and Mandrake
+   Linux systems.
+
+   If you don't have such a cron job, make one:

+   rpm -qa --qf '%{name}-%{version}-%{release}.%{arch}.rpm\n' 2>&1 \
+           | sort > /var/log/rpmpkgs
+
+   rpm completion will use this flat text file instead of the RPM database,
+   unless it detects that the database has changed since the file was created,
+   in which case it will still use the database to ensure accuracy.
