MKUSBBOOT(8) MKUSBBOOT(8) NAME mkusbboot - generate bootable USB or other disk image for PC SYNOPSIS mkusbboot [ -b boot ] [ -p proto ] [ -r root ] [ -s size ] DESCRIPTION Mkusbboot generates a bootable disk image, called image, from the filesystem at root (by default /n/boot), 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 con- sole on 386 (with optional VGA) or amd64 machines, when copied to a (possibly USB) disk. There is an nvram parti- tion, initially zeroed. EXAMPLES Create a bootable USB flash drive from the local Plan 9 installation. mkusbboot pump <image >/dev/sdU0.0/data Create a bootable disk from the local Plan 9 installation. mkusbboot -b /386/9load pump <image >/dev/sdC0/data FILES image the resulting disk image /sys/lib/sysconfig/usb plan9.ini and fossil.conf for the gener- ated system /sys/lib/sysconfig/proto/stand-usb default proto /env/objtype architecture of the default kernel in the disk image /tmp/9load files created while executing /tmp/9pccpuf.gz /srv/fossil /srv/fossil.open MKUSBBOOT(8) MKUSBBOOT(8) /srv/fscons /srv/fscons.open SOURCE /rc/bin/mkusbboot SEE ALSO usb(4), boot(8), 9boot(8), diskparts(8), loadfossil(8), partfs(8), plan9.ini(8), prep(8) BUGS Due to name clashes in /srv, should be run only on machines with no running fossil instance named `fossil' and thus no /srv/fossil, /srv/fossil.open, etc. Not all BIOSes can reliably read from USB devices. Your mileage may vary.
