43 utility allows specifying an alternate kernel and/or boot flags for the
44 next time the machine is booted.

48 information, it is deleted so in case the new kernel hangs the machine,
49 once it is rebooted, the machine will automatically revert to its previous
52 The options are as follows:
53 .Bl -tag -width ".Fl o Ar options"
58 option removes an existing
63 option disables the sanity checking which checks if the kernel really exists
68 This option specifies a kernel directory relative to
70 to load the kernel and any modules from.
73 allows the passing of kernel flags for the next boot.
76 .Bl -tag -width ".Pa /boot/nextboot.conf" -compact
77 .It Pa /boot/nextboot.conf

80 configuration is written into.
89 .Dl "nextboot -k GENERIC"

93 .Dl "nextboot -o ""-s"" -k kernel"
