[Bug 1251939] [NEW] Chroot fails with "Cannot chroot when not started as root" error

[Arul]

Public bug reported:

I have set my chroot directory as shown below.

ChrootDir /var/www

When started with the above chroot setting, apache2 exits with the
following error

[Sat Nov 16 13:52:40.621872 2013] [unixd:alert] [pid 3747] (34)Numerical
result out of range: AH02158: Cannot chroot when not started as root

NOTE: apache2 is started as 'root' user. This was reported as a bug in apache.org earlier (link below) where it was confirmed this is fixed in a trunk.
