Hello,

I have a firewall that is built pretty minimally on a P3 and
and old 4 gig ide disk:

/dev/hda3              2068348   1668104    400244  81% /
/dev/hda1               100728     40452     60276  41% /boot

I have a 4 gig Cf card (sandisk) and a ide-cf card that should
make the CF card look like an ide hard drive.

I've been searching for a wiki or something that describes the general
sequence of events to migrate the existing gentoo system to the
CF/ide disk, with no luck.

I did find this page:
http://gentoo-wiki.com/Mounting_a_block_device_with_JFFS2


But it seems vague(outdated) and missing many steps. Or
am I confused? I'm just looking for some outline or verbose
steps to replace an ide drive on a system with a CF/ide drive
and jffs2, as I have many systems that I'd like to do this with, 
for core reliability on minimalistic gentoo servers. I plan
on having additional space on these systems (when needed)
via NFS.


Any help or ideas are greatly appreciated.

As far as I know you won't need jffs2 (or any other fs for flash
memory). 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...
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.
