IIRC, these changes are needed atm (d-e-c 2.10.19) to enable amd64 LTSP:
(1) Run "ltsp-build-client --arch amd64" to create chroot and NBD image.
(2) Use "ldapvi -ZD '(cn=admin)'" to replace i386 with amd64 (dhcp
items).
(3) Run "service isc-dhcp-server restart".
(4) Edit /etc/debian-edu/pxeinstall.conf (set ltsparch=amd64).
(5) Run 'debian-edu-pxeinstall' to regenerate the PXE menu.
With amd64 beeing the default it would be similar, and instructions like
those above could be added to the Buster manual.
Also, to support other prospected archs, the dhcp values for rootpath
and filename shouldn't be hardcoded in LDAP (atm 'i386') but rather be
set at installation time, defaulting to the server arch. This could be
done with these changes:
