Just here is something new and I want to know why so that I am not supprised. Hi, the directory is intended for configuration files included by named.conf via include directive. After that the directory is mounted via `mount --bind` into chroot so you can just put files into /etc/named/, include them into named.conf and chrooted configuration will work for you out of the box (i.e. you don't have to create symlinks for files included by named.conf etc...)

RE: chroot/etc/named/ directory?
Haven't done it on RHEL/CentOS 6.x yet but in RHEL5 with the bind-chroot installed I've always had: /var/named/chroot as the jail for BIND. /var/named/chroot/etc = Location of global config files such as named.conf /var/named/chroot/var/named = Location of the zone files.

If you installed bind*-chroot, it will populate the /var/named/chroot hierarchy. I have been running chrooted since. Well probably when I switched from NT to Linux in '98. At first it was Whitehat, then Centos. I installed bind-chroot and though it built the /var/named/chroot tree, the only file is ~/etc/localtime, nothing else prepopulated. Well I DO have all my files from my current server to rsync over (over SSH so I don't have to actually run rsyncd), so it is no loss, just a question of where is everything. I seem to recall this tree in previous attempts to not be empty. Maybe they learned it is better for someone working here to do it all themselves... There are 'standard bind' files under /etc/nam* and /var/named to copy over if I choose (and find them more current than what I have from 2 years ago). It's not strictly required (though I would suggest it), but if you intend to run BIND chrooted /var/named/chroot is essentially /. Learned that some years ago. Familiar with how the tree is mounted. You'll have to place the usual things BIND needs to operate under that directory -- configs, zones, etc. Just seems that prior rpms came with a FEW files preset, like named.rfc1912.zones. But that was years ago and me brain is probably a little weak in the memory department. Assuming this came from the chroot RPM, you'll already have other essential pieces for chroot such as your null/random/zero devices. Yes. And there are a few under ~/dev/ Since you mention CentOS, you'll likely also want to pay attention to things like ROOTDIR in /etc/sysconfig/named. Came preset. I am assuming handled by the bind-chroot rpm. Having said all that, you might search the archives (SRPMS have been provided by community members) or other sources for a newer BIND while you're at it...9.8.2 isn't ancient, but also not technically up to date now. I am not up to building on my own and the few extra repos I work with (EPEL and rpmfusion) do not have a newer version all ready for Centos 6.3.

Just a check shows that #49 is fixed in what I have installed: https://rhn.redhat.com/errata/RHSA-2012-1268.html And #50: https://rhn.redhat.com/errata/RHSA-2012-1363.html So I would ASSuME that I can work with keeping my install current and will stay on top of things. At least for a while. And getting back to the start of this thread, until something shows up, I will just ignore that ~/etc/named/ directory thanks I would want to find it already in an rpm.
