Installation
echo "net-misc/ltsp X" >> /etc/portage/package.use emerge ltsp
Configuration
Kernel
Make sure your kernel has NFS Support!
Filesystems --> Network Filesystems --> NFS Server Support CONFIG_NFSD=y CONFIG_NFSD_V2_ACL=y CONFIG_NFSD_V3=y CONFIG_NFSD_V3_ACL=y CONFIG_NFSD_V4=y CONFIG_NFS_ACL_SUPPORT=y CONFIG_NFS_COMMON=y
Rebuild kernel and reboot.

PXE Boot / PXE Linux
The /pxelinux.cfg/ directory needs to be moved in order to work.
Before...
/tftpboot/
|-- lts
| `-- vmlinuz-2.6.17.8-ltsp-1
`-- pxe
| |-- bzImage-2.6.17.8-ltsp-1
| |-- eb-5.0.9-3c905c-tpo.lzpxe
| |-- eb-5.0.9-eepro100.lzpxe
| |-- eb-5.0.9-rtl8139.lzpxe
| |-- initramfs.gz
| `-- pxelinux.0
`-- pxelinux.cfg
`-- default
cd /tftpboot/ mv pxelinux.cfg/ pxe/
After...
/tftpboot/
|-- lts
| `-- vmlinuz-2.6.17.8-ltsp-1
`-- pxe
|-- bzImage-2.6.17.8-ltsp-1
|-- eb-5.0.9-3c905c-tpo.lzpxe
|-- eb-5.0.9-eepro100.lzpxe
|-- eb-5.0.9-rtl8139.lzpxe
|-- initramfs.gz
|-- pxelinux.0
`-- pxelinux.cfg
`-- default
Your /tftpboot/pxe/pxelinux.cfg/default file should look like this...
prompt 0 label linux kernel bzImage-2.6.17.8-ltsp-1 append rw root=/dev/ram0 initrd=initramfs.gz
Test Run #1
Start the software daemons on the server...
/etc/init.d/nfs start /etc/init.d/dhcpd start
Power on the desktop computer thin client. Go into the BIOS and change the settings to...
- Remove the IDE / SATA Hard Drive and CD-ROM
- Set the option for Network Boot capability
- Set the Boot Order to Network only
Save settings and reboot. You should now see the PXE Boot starting, assign an IP Address and load the ROM file from the server. Then it will load the linux kernel.
That's as far as I have got!
