Re: 2.6.28 headers break kbd and net-tools userspace builds

[Andrew Walrond]

Hey guys. A gentle nudge...

My distro scripts build the

   glibc
   iproute2
   iputils
   kbd
   lm_sensors
   net-tools
   strace

packages and others against every new release of linux and linux-stable, 
(hence my initial report).
Right now I'm stalled at the 2.6.27.? headers so can't do any more 
testing until this is resolved.
