Description Bojan Smojver 2012-10-04 22:43:45 UTC 
Description of problem:
As of recently, every time named-chroot gets restarted, there are new bind mounts that pop up on my system. So, today, I have:
--------------------
# mount | grep named
/dev/mapper/vg00-lv00 on /var/named/chroot/etc/named type ext4 (rw,relatime,seclabel,data=ordered)
/dev/mapper/vg00-lv00 on /var/named/chroot/usr/lib64/bind type ext4 (rw,relatime,seclabel,data=ordered)
/dev/mapper/vg00-lv00 on /var/named/chroot/etc/named type ext4 (rw,relatime,seclabel,data=ordered)
/dev/mapper/vg00-lv00 on /var/named/chroot/usr/lib64/bind type ext4 (rw,relatime,seclabel,data=ordered)
/dev/mapper/vg00-lv00 on /var/named/chroot/etc/named type ext4 (rw,relatime,seclabel,data=ordered)
/dev/mapper/vg00-lv00 on /var/named/chroot/usr/lib64/bind type ext4 (rw,relatime,seclabel,data=ordered)
/dev/mapper/vg00-lv00 on /var/named/chroot/etc/named type ext4 (rw,relatime,seclabel,data=ordered)

/dev/mapper/vg00-lv00 on /var/named/chroot/etc/named type ext4 (rw,relatime,seclabel,data=ordered)

Cannot reproduce this as of bind-9.9.2-2 (or was it the kernel that fixed it?). Closing.
