i386 clients not booting as thin client

[roman.meier@gismap.ch]

Hi folks,

I'm getting my feet wet with the latest version of Debian Edu 10.9.0.

I was able to prepare the server and additionally create the image for our i386 clients.

All our clients are booting nicely using primary and secondary subnet. However they only boot as "diskless workstation". In older versions of Debian Edu I was able to edit file /var/lib/tftpboot/ltsp/i386/lts.conf and add FAT_RAM_THRESHOLD=1000 for all clients having less than 1GB RAM to boot as thin client instead of diskless workstation. This is not working for me anymore.

I also tried to edit LDAP settings using ldapvi. I added the following entry: 
ltspConfig: FAT_RAM_THRESHOLD=1000
This also doesn't work for me.

Any ideas how to fix this?

Kind regards,
Roman
