How can I set up custom cmdlines and stuff?
There are three configuration variables that control the booting process: • boot-device – This is the device and file path to the kernel. Example: disk:\boot\vmlinuz or nand:\boot\vmlinuz • boot-file – This is the kernel command line (the unfortunate name is historical) Example: quiet root=sda1 rootfstype=ext3 • ramdisk – This is the device and file path to the initrd. If null, no initrd will be loaded. Example: disk:\boot\initrd.img Their default values are suitable for booting from a USB storage device. As described above, boot-configure will set the values of these variables to baseline values typical for the first device that has either /boot/olpc-boot.fth or /boot/vmlinuz , trying USB first and then the internal flash memory.
