In the past couple of summers I have offered suggestions on how to strip down a current kernel and run it extremely light, and this summer I see no reason to break with [...]

As I have mentioned in the past, one of the joys of working with older hardware is that I rarely need to keep up with kernel [...]

so “Compile the kernel with frame pointers” is good just for debugging, otherwise is better “without”

I think the reverse is usually what happens — the entire kernel with all of the options is built, and then when the appropriate hardware is sensed, the modules are inserted. I like to think that this way is faster and lighter, but I’m definitely no expert. Either way, I would still prefer to build it myself. I’m a glutton for punishment. :twisted:

I had a tendency a year ago to leave in as many network options because I wasn’t sure what they did. Lately though I took the time to read the help pages and try kernels without a lot of those, and with the exception of Unix sockets, a lot of it can be discarded. Otherwise, there are a few changes in the General setup area. Most of the rest is the same though.

It’s probably bad practice, but I’m more likely to grab a dot-release kernel when it’s updated, than to patch and rebuild a kernel for a security patch. Part of that is because it takes around an hour to compile one of these, but partly because I’m lazy. … :(
