There are no prizes for guessing its application. I'm now in a situation where I'd like to update those patches to cope with a new version of the hardware they reference. My problem is that in the intervening time, the whole Balloon world has changed a couple of times, and neither I nor anyone else has kept the patches up to date with either the new build system or current kernel versions. I would like to do this update with minimum possible effort and the smallest possible change set. The application doesn't care about being on the bleeding edge, and the old kernel (2.6.29.1) does its job just fine. However, I'm prepared to come kicking and screaming into the present day if it'll pay dividends now or in the future. I vainly tried an 'svn up' on my ancient checkout of trunk, which failed miserably because so much has changed. I'm currently building the podpoint variant of the '1.0-stable' branch, which seems to be working. My question: is it permissible or indeed advisable to make modifications in the 1.0-stable branch with kernel 2.6.29.1, or somewhere else, or somehow coax everything into menuconfig2 and a modern kernel? The thought of getting the device drivers working with a different kernel fills me with horror. There are enough variables in this project as it is, and I don't want to spend any more late nights on it.
