I have been able to install Fedora (12) on an SD card and run that on a Sheevaplug Dev
kit. There is a good bit of info on the web but I wasn’t able to find it all in one place. So
I thought I’d write it all down.

#First lets prep the SD card:
######################################################
Inser the SD card to your linux system, tail dmesg to find out how your system saw it:
[root@wigeon ~]# dmesg | tail
scsi 8:0:0:0: Direct-Access HP v100w 4096 PQ: 0 ANSI: 0 CCS
sd 8:0:0:0: Attached scsi generic sg2 type 0

sd 8:0:0:0: [sdb] Assuming drive cache: write through
sdb: sdb1
sd 8:0:0:0: [sdb] Attached SCSI removable disk
[root@wigeon ~]#
Next run fdisk to create the partition table. I created one large partition skipping swap, no
need to swap on to an SD card.
[root@wigeon ~]# fdisk /dev/sdb
The number of cylinders for this disk is set to 1125.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
(e.g., DOS FDISK, OS/2 FDISK)

Edit the fstab to boot off of the SD card.

Change the / partition to:
/dev/mmcblk0p1 / ext2 defaults 1 0
Edit the /etc/shadow so root can login, I don't know roots pw, we will make it empty.
[root@wigeon tmp]# vi /media/flash/etc/shadow

#Post install notes
#######################################################
I installed dnsmarq as an internal dns server, its lighter weight than bind
I installed ntpdate, and ntpd to set the date
CHANGE THE ROOT PASSWORD!!! Add a new user and install sudo
Disable root login in /etc/ssh/sshd_config
I still can't get the right modules for iptables to load....
The little sheevaplug is fast and fast enough for a home server.
Hope this helps someone.
