How exactly is this going to be implemented? Is the tool going to write to a |
| 12 |
config file or create a symlink /usr/src/linux-output for example? Don't forget |
| 13 |
that the user would have to still be able to easily compile a kernel on their |
| 14 |
own using the methods they are used to, i.e. make config, make menuconfig, make |
| 15 |
all, etc. I've been using a similar system on some of my machines (some where I |
| 16 |
don't have nvidia cards), and I implemented it the following way: |
