I have this line in /etc/sysctl.conf:
net.netfilter.nf_conntrack_tcp_loose=0

But after reboot it reverts to default value 1.
csrv:~ # sysctl -a | grep loose
net.netfilter.nf_conntrack_tcp_loose = 1

The only one netfilter option net.netfilter.nf_conntrack_tcp_loose reverts to
default.
Other netfilter options, like net.netfilter.nf_conntrack_max, preserves their
values.

If i run "service network restart" or "service SuSEfirewall2 restart" option
net.netfilter.nf_conntrack_tcp_loose not changed.

Reproducible: Always

Steps to Reproduce:
1. add net.netfilter.nf_conntrack_tcp_loose=0 to /etc/sysctl.conf
2. reboot
3. check value: sysctl -a | grep loose
Actual Results:  
net.netfilter.nf_conntrack_tcp_loose reverts to default value 1.

Expected Results:  
net.netfilter.nf_conntrack_tcp_loose=0.
