* Read through the dhcpcd.conf file and change things as needed
* For kernel to be able pick up 2 other root-paths for HDD backup-restoration system I built two diferent custom kernels with initrd kit. I also modified one script in initrd kit to let compiled kernel to pick 2nd or 3rd root-path from dhcpd.conf at boot time. I'm sure there is an better way to supply different root-paths to kernel at boot time I just haven't had enough time to dig into it so I made ugly quick-hack that worked for me.
* Protect some menu entries with md5 passwords or clear the fields for no passwords operation
I will write howto for partimage-ltsp hdd backup-restore system probably next week and I'll post it then.
Dos network boot is done with the great modular dos network bootdisk from Bart!
See http://www.nu2.nu/bootdisk/network/
I made an floppy with Bart's stuff and configured it as needed. Then made image (dosnet.eb) out that floppy with dd and put it to /tftpboot/dos/dosnet.eb. Dhcpd.conf is containing an entry to load dosnet.eb image at boot if needed.

Hi, I?m also very interested in that.

It consists of bit advanced dhcpd.conf file which presents an boot menu at terminal boot time - choices are: 1) Linux terminal 2) First HDD partition (usually windoze installed there) 3) HDD image restore from server 4) HDD image backup to server 5) Automated windoze install (dos network boot with dhcp, domain logon, mounting install share, totally automatic win98se install, applications automatic installs, etc) 6) floppy boot All menu entries can be md5 password protected. HDD image restore/backup is done with partimage (www.partimage.org). If you want to know exactly how it was done in details - then let me know. Ill then try to write it down in details...it might take coupple days to find a spare time and write an howto. But I gotta do it someday anyway...:O)
