Hi Petr,

This is exactly what I need.

Due to some reasons, the txt-record is used to store additional
information for kickstart.
Therefore when I need to spin up new VM I need to update DHCP (static
record) + txt-record.

SIGHUP will reload DHCP configuration, however, txt-record is part of
core configuration, therefore it will not change.
The only possible way is to restart the whole DNSMASQ which is
something that I'm trying to avoid.

I asked if someone doesn't have some useful tips on how to avoid this scenario.
It seems that I will need to use DNSMASQ for DHCP and BIND for DNS resolution.

Regards,
Martin
