Re: [Ltib] Auestion regarding ltib.preconfig configuration changes and how to have LTIB follow it

[Stuart Hughes]

Hi Peter,

Thanks for the patch, I've checked that into CVS.

Could I ask that in future you attach patches as a unified diff.  I find
context diffs hard to follow, and inline patches get mangled by my mail
client(s).

All: please let the list know if you see any regressions related to
initial install (package list), or --hostcf behaviour.

Regards, Stuart
