3.2.2. boot - boot from script, device, …¶
boot [-vdlmMwt] [BOOTSRC...]
This is for booting based on scripts. Unlike the bootm command which can boot a single image this command offers the possibility to boot with scripts (by default placed under /env/boot/).
BOOTSRC can be: - a filename under /env/boot/ - a full path to a boot script - a full path to a bootspec entry - a device name - a partition name under /dev/ - a full path to a directory which - contains boot scripts, or - contains a loader/entries/ directory containing bootspec entries
Multiple bootsources may be given which are probed in order until one succeeds.
Dryrun. See what happens but do no actually boot
