# A simple command script to reboot into a secondary OS.

# Tips:

# The path to the right command folders might need to be

# included. Mine shell script could not find grub-reboot.

#

# The name of the target operating system can be found

# inside /boot/grub/grub.cfg

#

# By setting the ownership to root and the script only

# executable by root the command can only be run by sudo,

# or likewise, which is needed for grub-reboot. Makes it

# impossible to forget sudo and run the command without

# the boot order changed.
