It is meant to be used on embedded devices that directly access the flash memory. In your case, the CF-disk takes care of wear leveling. Just use ext2. However, you could still get problems because, as far as I know, wear leveling needs to be tuned for the FS and most probably no one tuned the CF-disk for ext2. Maybe you could use fat instead... signature.asc Description: This is a digitally signed message part

I did this sort of system a while ago. I've used 1GB card with gentoo and cf-ide adapter. There are some tricky parts that nobody mentions. One of them is that I wasn't able to boot from my 1GB hard drive when it was connected via 80 pin ide cable, I've dig up some old 40 pin ata cable and it worked. Other things you have to remeber concern file system usage, you musn't create swap partition, disable local syslog, log rotation, turn everything except desired daemons etc. regards dexter

James You shouldn't need to do anything special - just copy all files over exactly, and then set up GRUB on the CF card. Your biggest problem is you need to cut 75% from your installation. Delete portage, logs, and so on to do so. You can mount portage from NFS later. You might also have to uninstall X and all desktop environments to get it that small -- assuming you can do so, it's a good idea. -- gentoo-user@lists.gentoo.org mailing list
