grml2usb(8) ========== Name ---- grml2usb - install grml ISO(s) on usb device for booting Synopsis -------- grml2usb [ options ] ******************************************************************************* Important! The grml team does not take responsibility for loss of any data! ******************************************************************************* Introduction ------------ grml2usb installs grml on a given partition of your usb device and makes it bootable. grml2usb provides multi-iso support, meaning you can specify several grml ISOs on the command line at once and select the grml flavour you would like to boot on the bootbrompt then. Notice that the default ISO (that's when pressing just enter on the bootprompt or wait until the timeout matches) will be the *first* one specified on the grml2usb command line. Options ------- The ISO[s] might be the path to one or multiple grml-ISOs as well as the path to the currently running live-system (being /live/image). The device either might be a device name like /dev/sda1 or a directory. When specifying a device name the device is mounted automatically. When specifying a directory it won't be touched but instead grml2usb is assuming that you did set up a bootloader on your own and a bootloader won't be installed automatically. The following options are supported: *--bootoptions=...*:: Use specified bootoptions as default. *--bootloader-only*:: Do *not* copy files but instead just install a bootloader. *--copy-only*:: Copy files only but do *not* install a bootloader. *--dry-run*:: Avoid executing commands, instead show what would be executed. Warning: please notice that the ISO has to be mounted anyway, otherwise identifying the grml flavour would not be possible. *--fat16*:: Format specified partition with FAT16. **Important:** this will destroy any existing data on the specified partition! *--force*:: Force any (possible dangerous) actions requiring manual interaction (like --fat16). *--grub*:: Install grub bootloader instead of syslinux. [Notice: not implemented yet.] *--help*:: Display usage information and exit. *--initrd=...*:: Install specified initrd instead of the default. You might want to specify option *--kernel* as well. (Be aware when using multiboot setup.) [Notice: not implemented yet.] *--kernel=...*:: Install specified kernel instead of the default. You might want to specify option *--initrd* as well. (Be aware when using multiboot setup.) [Notice: not implemented yet.] *--lilo=...*:: Use specified lilo executable to for installing master boot record (MBR) instead of the default, being /usr/share/grml2usb/lilo/lilo.static. *--mbr*:: Install a default master boot record (MBR) on the device. *--quiet*:: Do not output anything but just errors on console. *--squashfs=*:: Install specified squashfs file instead of the default. [Notice: not implemented yet.] *--uninstall*:: Uninstall grml ISO files. [Notice: not implemented yet.] *-v*, *--version*:: Return version and exit. *--verbose*:: Enable verbose mode.

Note: boot "grml" as usual, for booting grml-small use "grml-small on the bootprompt, for grml64 use "grml64" and so on... The *first* specified ISO is the one being the default (when just pressing enter or waiting until the timeout is reached). # grml2usb --fat16 --mbr /home/grml/grml_2008.11.iso /dev/sdb1 Install specified ISO on device /dev/sdb1, install MBR on /dev/sdb and format partition /dev/sdb1 with FAT16 filesystem. # grml2usb --grub /home/grml/grml_2008.11.iso /dev/sdb1 Install specified ISO on device /dev/sdb1 and use Grub as bootloader (instead of syslinux being the default). # grml2usb --kernel=/boot/vmlinuz-2.6.28-grml --initrd=/boot/initrd.img-2.6.28-grml \ /home/grml/grml_2008.11.iso /dev/sdb1 Install specified ISO on device /dev/sdb1 but use given kernel and initrd instead of the ones provided by the ISO. # grml2usb --squashfs=/grml/grml-live/grml_cd/live/grml.squashfs \ /home/grml/grml_2008.11.iso /dev/sdb1 Install specified ISO on device /dev/sdb1 but use given squashfs file instead of the one provided by the ISO. # grml2usb --bootoptions="lang=de ssh=mysecret" grml_2008.11.iso /dev/sdb1 Install specified ISO on device /dev/sdb1 and use "lang=de ssh=mysecret" as default bootoptions.
