[webmin-l] Method of writing to BIND files

[Marcus F. <mar...@gm...>]

Hello,

Question to Webmin devs. I need to know how Webmin writes to BIND files
when config or zone is modified from the GUI, specifically I'm interested
for these files:
1. /etc/bind/named.conf.local
2. /var/lib/bind/*

Does it modifies the file in place or it replaces the file with new one at
once?

We run rsync to backup these files. Normally, if the file is being written
to, rsync will copy whatever data is there, no matter if the process of
writing is not completed. If Webmin updates the files by modifying the file
in couple of writes, the backup will contain incomplete files.

Thank you in advance!
