[Rdo-list] Issues with sysctl.conf settings on CentOS 6?

[Steve Gordon]

Hi all,

Running packstack --allinone on a freshly installed and updated CentOS 6.5 system I encountered this error with sysctl.conf:

"""
Applying 192.168.122.152_neutron.pp
192.168.122.152_neutron.pp:                       [ ERROR ]

Running `sysctl -p /etc/sysctl.conf` myself I receive:

"""
# sysctl -p /etc/sysctl.conf

net.ipv4.conf.default.rp_filter = 1

Removing the errant lines and re-running PackStack it just adds them back and thus fails for the same reason. I couldn't find another RDO bug covering this issue, has anyone else run into it?

Thanks,
