![]() ![]() This is required when you boot a USB device. scandelay=x: pauses x seconds during the startup to allow slow devices to initialize.nonet: this will disable the network auto detection at startup.Use this option if you have a problem when the system loads a particular module. noload=xxx: prevents loading kernel modules, multiple comma separated occurrences are permitted (example: noload=3c59x,e1000).doload=xxx: loads needed kernel modules, multiple comma separated occurrences are permitted (example: doload=3c59x,e1000).dodebug: Enables verbose messages in linuxrc.Hardware, drivers and troubleshooting options ΒΆ This is because the boot partition is what Grub2 will consider as its root partition during the boot process. If you have a separate boot partition mounted on /boot and if you copy this ISO image to /boot/sysrcd/systemrescuecd-x86.iso then the option has to be isoloop=/sysrcd/systemrescuecd-x86.iso. The path of the ISO image may be different from the path on your linux system. This option specifies the path of the ISO image in the partition that grub considers as its root partition. For that reason, this isoloop=xxx boot option is required in your grub.cfg. When booting an image, SystemRescueCd must be aware that its sysrcd.dat file is in an ISO and not directly on the partition. If you put a copy of systemrescuecd.iso on a partition that Grub2 can read then you can boot SystemRescueCd directly from the ISO image stored on your hard drive. isoloop=xxx: Grub2 will boot from an ISO image which is stored on the hard disk.Change the path by using backstore=/sysrcd/mybackstore.bs. The default location for a backing-stores file is any file named sysrcd.bs located at the root of a disk which is often a USB stick. If you want to save your backing-store file on a harddisk, boot with backstore=alldev to scan all devices (not just removable devices). To disable the disks scan at boot time specify backstore=off on the boot command line. A backing-store is not mandatory and if the scan fails, it will store the files which have changed in memory. By default, sysresccd automatically scan removable devices (eg: USB sticks) at boot time and uses the first backing-store it finds. A backing-store saves all the changes you can make, so that you keep these changes the next time you boot. backstore=xxx: SystemRescueCd comes with support for the backing-stores.All the actions that are supported by an initscript can be used. Use this option a multiple of times for different services. ![]() This does the same thing as /etc/init.d/samba start. For instance if you need the samba service to be started, you can boot with: initscript=samba:start.
