More Linux Legalese

Creating a Bootable CompactFlash

  • A CompactFlash has limited write life cycle
    • do NOT write to it unless you have to

  • you will need a CompactFlash adaptor to either usb or IDE connectors

Using the CompactFlash as a regular IDE disk
  • Benefits
    • no moving parts ( no hard disk )

Using /dev/ram (initrd) to boot the rootfs ( /dev/ram or /dev/loop )
  • you are restricted to the size of the ramdisk

  • Benefits
    • you MIGHT be able power off anytime ( check what is mounted as rw )
    • linux runs in memory
    • the rootfs cannot be compressed
      • you cannot create a 8MB rootfs within a 4MB /dev/ram initrd

Using /dev/loop (initrd) to boot the /dev/loop rootfs
  • you can use any size initrd and rootfs

  • Benefits
    • you CAN power off anytime
    • linux runs in memory
    • the rootfs can be saved/transferred compressed and decompressed when booting
