You could built-in an initramfs into your kernel - see here: http://wpkg.org/Running_Debian_on_Freecom_FSG-3#initramfs (and FSG-3 downloads for an example initramfs; it's ARM-based, but you've got an idea). > I am already thinking of using several USB sticks... when I am at a linux > user group party, I just put in an WLAN router USB stick and when I am at > some my ADSL routing USB stick... so the internal flash would just be > the "bootloader" ;-), well lets see.. > BTW how fast is your USB?

A really cheap 4 GB USB stick: # echo 3 > /proc/sys/vm/drop_caches mangoo:~# hdparm -Tt /dev/sda /dev/sda: Timing cached reads: 84 MB in 2.01 seconds = 41.78 MB/sec Timing buffered disk reads: 24 MB in 3.14 seconds = 7.63 MB/sec BTW, you don't want to repeat "hdparm -tT /dev/sda" one after another - you'll get cached results, i.e.: # hdparm -Tt /dev/sda /dev/sda: Timing cached reads: 94 MB in 2.03 seconds = 46.25 MB/sec Timing buffered disk reads: 28 MB in 3.20 seconds = 8.76 MB/sec Also, you will want to drop the caches between making any tests. On the other hand, as this router has only few RAM, caching effect is rather limited. -- Tomasz Chmielewski http://wpkg.org |
