Hi Todd,
It should not be deleted. It is packaged contents of usr/share/GeoIP/, just bind mounted
into /var/named/chroot when named-chroot.service is running. As soon as it stops, it is
unmounted.
mount --bind means it does not use more space. It can be a bit confusing, but those files
are still only once saved on disk. But the same files are visible in /usr/share/GeoIP and
/var/named/chroot/usr/share/GeoIP.
It can be verified by commands:
stat /usr/share/GeoIP/
stat /var/named/chroot/usr/share/GeoIP/
It has the same values, including Inode. That means it is the same directory, just in
another location.
If you do not need it, you can comment out /usr/share/GeoIP in /etc/named-chroot.files
But it would not free any space, because it did not took any. It would just presenting
that directory in chroot.
