I'm replying to a really old email, because I - once again - installed this silly script that you wrote several years ago on a new machine.
So Bruce - how about we add this script to the kernel "tools" directory, because it's actually very useful for anybody who uses CONFIG_LOCALVERSION_AUTO like I do (and clearly you at least used to do too).
I think CONFIG_LOCALVERSION_AUTO is really nice for various reasons (not the least of which is just doing thing like
gitk $(uname -r)..
but also because it makes it easy to go back to previous kernels when you're working on bisecting stuff etc).
I'll happily commit it as "tools/prune-kernel" or similar, but would like to get an ok from you as the original author.
And if somebody has improvements for specific distros, maybe the script will start getting improvements. And I won't have to copy it from an old machine every time, because it will just be there with the kernel source tree (and without a kernel source tree it's not needed).
