kexec-chooser

If you are looking for an efficient way to upgrade your Debian kernel, look no further than kexec-chooser. This small utility is a lifesaver when it comes to warm rebooting into new kernels. It seamlessly integrates recent Linux kernels' kexec feature, which allows you to load a new kernel image into memory and boot into the kernel directory without having to do a full reboot of the machine. This means that you can speed up reboots significantly and handle kernel upgrades more quickly.

With kexec-chooser, you can easily choose which kernel version you want to reboot into. For example, using the command kexec -l, you can easily print a list of available kernels. Then, by specifying the version you want to warm-reboot into with kexec 2.6.17, kexec-chooser will indicate that you want to reboot to that specific kernel version. It's important to note that this won't reboot your machine automatically. Instead, when you reboot via the reboot command or GNOME's Shut Down/Reboot dialog, kexec-chooser will kick into action and warm-reboot into the kernel version you specified.

Overall, kexec-chooser is a valuable utility that makes upgrading your Debian kernel a breeze. With its simple yet effective commands, you can effortlessly warm-reboot into new kernel versions without the hassle of a full reboot.
