If one has a BBB which normally boots from eMMC is it possible to
write a script that will reboot from the microSD card?

What I want to do is allow the eMMC to be cloned to somewhere (across
the network) automatically overnight.  If the switch to boot from
microSD is possible this shouldn't be too difficult.

The sequence would be something like:-

    Have cron run a script in the small hours.

    Script shuts down system on eMMC and reboots from SD card

    SD card system clones an image of the emmc to an external system
    somewhere.

    SD card then shuts down and reboots from eMMC
