kexec-chooser is a small utility that makes warm rebooting into new kernels under Debian a bit easier.

Recent Linux kernels support a new feature called kexec. Basically it allows you to load a new kernel image into memory, and then boot into that kernel directory without having to do a full reboot of the machine. This can speed up reboots significantly.

Usage:

kexec -l

will print a list of available kernels.

kexec 2.6.17

will indicate that you want to warm-reboot into the 2.6.17 kernel. Note that this won’t actually reboot your machine. When you reboot via the reboot command, or GNOME’s Shut Down/Reboot dialog, then kexec-chooser will warm-reboot into the kernel you specified.
