--dhcp-hostsdir --dhcp-optsdir and --hostsdir work in much the same way
as when the first three options are given a directory; the files are
read at start-up and when SIGHUP is received. BUT any file which is
modified or created gets read asynchronously, without needing SIGHUP to
be sent. Note that the old data from the files is not discarded when
this is done: if a file gets modified, then it gets re-read but data
from the previous version of the file is not deleted. This means that
Why is deleting not happening when the file is reread?
this facility is useful for adding hosts to the configuration without
the upheaval of a full SIGHUP re-read. Anytime you want to delete
stuff,
SIGHUP is still needed.
In other words, what is the reasoning behind requiring SIGHUP to delete
stuff?
The cache datastructures don't allow track where names came from, so the
choices are to clear the cache and re-read all configuration files, or
not to delete anything.
Thank you, that would explain the following:
inotify, new or changed file /etc/dnsmasq-dhcp-hosts.d/try
read /etc/dnsmasq-dhcp-hosts.d/try
duplicate dhcp-host IP address 172.17.232.10 at line 7 of
/etc/dnsmasq-dhcp-hosts.d/try
duplicate dhcp-host IP address 172.17.232.11 at line 9 of
/etc/dnsmasq-dhcp-hosts.d/try
Is there a way to disable inotify?
Use dhcp-hostsfile=</path/to/directory>instead of
dhcp-hostsdir=</path/to/directory>
dhcp-hostsfil is fine with a directory argument, and doesn't implement
the automatic re-read function.
Thank you.
Changing 'dhcp-hostsdir' and 'dhcp-optsdir' to 'dhcp-*file=<...>' works
but not for 'hostsfile=<PATH-OF-DIR>'

That is, if I'm reading the manpage correctly! :)
My apologies for the noise if this is already fixed in a newer release.
