Boot time menu option to set/disable auto array start

[tjb_altf4]

95% of the time I want the array to auto start, but it is a little painful constantly changing the autostart option for one off events like maintenance tasks or upgrades.

 

On the occasions I don't want auto array start after a reboot (say I've just installed new hardware), the idea of this feature would be to allow me to choose array autostart to be disabled at boot menu time, e.g. a syslinux config option.

 

Bonus points if this is implemented in a way that allows the dev team to set "next boot mode" to cater for events like after an Unraid OS upgrade (one of the main times disabling auto-start is important IMHO), or a dirty shutdown.

This is how the config might look in Syslinux config screen (which would reflect boot options)
