====== Suspend to disk and reboot ======

In order to easier switch between different operating systems on a pc, one can suspend to disk and configure grub to automatically reboot after suspending.


The command ''s2disk'' has options to easily trigger a reboot after suspending. This command is part of the ''uswsusp'' package on debian systems.
<code>
apt-get install uswsusp
</code>

An example script to suspend to disk and reboot immediately is:
<code>
#!/bin/sh
sudo grub-set-default 2 # here '2' is whichever option is Windows
sudo s2disk -P 'shutdown method = reboot'
</code>

The file ''/etc/default/grub'' contains the main configuration and the default entry for the linux system - usually 0. This will then ensure that after rebooting from windows, the linux system will be loaded again.
