mkusbboot - generate bootable USB or other disk image for PC mkusbboot [ -b boot ] [ -p proto ] [ -r root ] [ -s size ] Mkusbboot generates a bootable disk image, called image , from the filesystem at root (by default /n/boot ), but could be
.BR /n/sources/plan9 ),
using the mkfs (8) prototype file proto and files in /sys/lib/sysconfig/usb . The default boot program is /386/9loadusb .

The image will be exactly size *1,000,000 bytes long. By default, it will be 1,900,000,000 bytes long, so it should fit on so-called 2 GB USB devices. When building from /n/sources/plan9 , the image defaults to 900,000,000 bytes long, to fit so-called 1 GB USB devices.

The image contains 9fat and fossil (4) file systems and is configured to be bootable as a CPU server with serial console on 386 (with optional VGA) or amd64 machines, when copied to a (possibly USB) disk. There is an nvram partition, initially zeroed.

Create a bootable USB flash drive from the local Plan 9 installation. .EX mkusbboot pump <image >/dev/sdU0.0/data

/rc/bin/mkusbboot usb (4), boot (8), 9boot (8), diskparts (8), loadfossil (8), partfs (8), plan9.ini (8), prep (8) Due to name clashes in /srv , should be run only on machines with no running fossil instance named .LR fossil and thus no /srv/fossil , /srv/fossil.open , etc.

Not all BIOSes can reliably read from USB devices. Your mileage may vary.
