    To add to that (off-topic); To use flash disks efficiently you
    really need to look into MFS (Memory File System) as flash disks
    do not like alot of writing, logs and the like will chew it up
    if you are unlucky.

    Flash disks generally do around 1 million writes pr sector
    before a sector goes bad and the disks integrity is in question.
    Although for a setup-and-forget system do run tests on the amount
    of writes/sector of the type of flashdisk because it varies -alot-.
    Some are cheap and allows only a few hundred thousand, others permit
    much more.

    Besides once you have it up and running you can do upgrades by simply
    ftp'ing a new thoroughly tested MFS file to the router and reboot.
    This method isnt limited to flash disks either.

    Going back on to topic, i've successfully used both Zebra and the
    off-spring Quagga in uptime critical environments with multiple
    full-table feeds.
