# NOTE: dnsmanagerd writes bind9 files in $DNSMANDIR and with a suffix ".wip" then moves them

# for example by copying it to the secondary DNS server while the zone not being
|
|
# fully written to the file.
|
|

|
|
# Therefore, the different interesting actions we should monitor are:
|
|
# - moved_to: a zone file has been modified
|
|
# - delete: a domain has been removed
