My target platform/distro uses IPK and I have a local kernel
recipe which is based on the pre linux-yocto recipe that was
used by Poky.  When I build & package the kernel, I have
terrible performance - this is new, it used to be just fine.

Here's what I mean.  Building for my kernel and timing the
various steps, e.g.
   % time bitbake virtual/kernel -c compile

My kernel:
   compile            1m49s
   deploy             0m16s
   populate_sysroot   0m38s
   package           23m20s

Just to compare, using OTS Poky for BeagleBoard:
   compile            5m07s
   deploy             0m36s
   populate_sysroot   0m29s
   package            5m02s

That's a five-fold difference in the time to build & package
the kernel.

What am I doing [wrong?] that makes this so?
Would it be better if I switched to RPM like the BB is using?
