Hello!
The equipment that sends messages to the pager watch is being upgraded
to a Linux based embedded computer.
I implemented the ramdisk root filesystem technique as described in Paul
Moody's embedded mini HOWTO at:
http://users.bigpond.com/paulmoody/Mhow11c.html on a Radisys EPC-33 and
a 40M Sandisk flash drive.
>From the HOWTO:
> The kernel loads an initial ram disk initrd.img and mounts it as root.
> linuxrc script is executed. This script mounts /dev/hda1 ( the flash
device )
> and uncompresses a compressed 40 Mb root file system image stored as
> a conventional file hda1 into a 40Mb ram disk (dev/ram).
> The flash device ( /dev/hda1 ) is unmounted.
> When linuxrc terminates the initial ramdisk is unmounted and /dev/ram
> is mounted as root.
> The system now boots as per a normal boot sequence as though it was
> booting from a normal drive.
My question:
Is there any good reason not to just use the compressed 40M root
filesystem as the initrd.img and forget about the linuxrc step?
