we have to repair some embedded systems with mac addresses within a 
specific range.
These system needs bootp to get flashed some special software.

So i configured the following entries (Dnsmasq version 2.40):


Imho the device, who fits to the mac range, will receive the address for 
embed with a lease time of 10 minutes

Also i have a bootp entry:


Everything works well with one system but the address won't be released 
after 10 minutes.
When i replace the system with another one from the mac range i get the 
following error:

  dnsmasq[21376]: BOOTP(eth23) 00:9a:7e:8f:19:5a address 
in use

I always have to remove the lease entry manually from 
/var/lib/misc/dnsmasq.leases and restart dnsmasq to get the new system 
running, independently from how long i wait.
