DHCP lease and renovation

Hi we are deploying a distributed system with terminals running debian-live with is loaded at boot time via PXE: tftp + dhcp + nfs

Everything works mostly as desired but we had found that terminals never tries to renovate its lease.

Any idea of what can be wrong since, because we would like it to work as an regular dhcp client ( actual, when terminals are up they aren't aware at all about dhcp)

Right now we are working configuring permanents leases but it will help us a lot if we can have lease renovation.

This one of the boot files:

label kernel
        kernel debian-live/auto/vmlinuz-2.6.32-5-686
        append initrd=debian-live/auto/initrd.img-2.6.32-5-686 panic=180 boot=live config timezone=Europe/Madrid locales=es_ES.UTF-8 keyboard-layouts=es netboot=nfs nfsroot=10.0.10.50:/smartion/releases/auto  terminal-type=MSI hostname=CAMA2019 rsyslogserver=10.0.10.50 swapon watchdog


This are the logs of the DHCP ( dnsmasq)  and tftp  and NFS: when I boot a terminal

I would appreciate any hint about what we are doing wrong regards
