Red Hat Bugzilla – Bug 451450
bind-chroot update overwrites user supplied ROOTDIR setting
Last modified: 2014-11-21 12:13:15 EST
+++ This bug was initially created as a clone of Bug #227600 +++
Description of problem:
The bind update overwrites any settings like
with the default ROOTDIR
Version-Release number of selected component (if applicable):
3/3 on FC6, 1/1 on FC5
Steps to Reproduce:
1.Use a custom ROOTDIR
2.upgrade bind packages
ROOTDIR gets reset
Should not touch uncommented ROOTDIR setting
Hit me on FC5/FC6 alike and for consistency (?) filed under devel.
If the ROOTDIR is not to be changed by the user it should be hardcoded and not
part of sysconfig files. Otherwise the user's choice needs to be preserved.
Together with bug #226982 this bind update causes lots of grief on
(semi-advanced) bind/ldap server setups.

Could you tell me if this problem is caused by replacement of
/etc/sysconfig/named? And if old configfile is saved as .rpmnew? Thanks much, Adam

Also the full output of rpm -Uvv bind-*rpm would be helpful, is this 100%

I found the bug, see below. It is 100% reproducable, and is not related to rpm

After the update there is only the "new" /etc/sysconfig/named with the wrong
ROOTDIR in place, no *.rpmsave, *.rpmnew etc.
I took a closer look and found the bug (or feature): If bach-chroot is installed
on each upgrade of bind (which of course updates the bind-chroot subpackage) the
ROOTDIR is always reset to /var/named/chroot by
The script seems to want to preserve ROOTDIR if found in /etc/sysconfig/named,
but fails due to setting BIND_CHROOT_PREFIX to the default value early in the
script and later only looking at ROOTDIR if BIND_CHROOT_PREFIX is empty, e.g. never.
The easiest fix is probably simply unconditionally calling rootdir at the top of
bind-chroot-admin is going on with monopolizing ROOTDIR by removing it
completely when uninstalled. That should probably only happen iff ROOTDIR was
still the default.
Bottom line is: If one installs the current bind-chroot one is tied to
ROOTDIR=/var/named/chroot for as long as bind-chroot is installed. If this is
indended behaviour it should be loudly commented as such in
/etc/sysconfig/named. But I think the intended behaviour is to honour user
I suggest to source /etc/sysconfig/named at the very top and eliminate
BIND_CHROOT_PREFIX in favour of ROOTDIR everywhere.

Perfect catch. I've improved bind-chroot-admin script in fedora devel. Could you
tell me if problem is now solved, please? (with bind*-9.3.4-5.fc7, package will
be avaliable during day)

This could be fixed in bind-*9.3.4-3.fc6 . If this problem still exists, please
Looks like this fix didn't make it into RHEL. I got all my RHEL servers silently
knocked out by this upon upgrading from 5.1 -> 5.2.
You are right, fix is in Fedora but currently not in RHEL

My developer licenses do not include support or a support representative.
Still I think that if a package malfunctions on upgrades due to the user having done allowed customizations to the config files and when this package is as crucial as a domain name server it should be fixed in RHEL5 and not RHEL6.
Note that this behaviour has affected production systems that serve name zones. The failure is silent and asynchronous to the upgrade, which makes for access denials to the zone in question after the TTLs expire, which can be up to several days. So adding to the high impact this bug has you also have a lengthy diagnosis as cause and effect are separated.
