Hi!

I need to add in script some custom commands into /etc/rc.local file 
located in CT filesystem in order to execute them on CT start up. It 
needs to be done under regular user with full root rights granted via 
sudo. But "permission denied" error appears.

$ sudo echo "# oneadmin test" >> /vz/private/164/etc/rc.d/rc.local
-bash: /vz/private/164/etc/rc.d/rc.local: Permission denied

$ grep -v ^# /etc/sudoers|grep -v ^$

$ sudo id

groups=0(root),1(bin),2(daemon),3(sys),4(adm),6(disk),10(wheel)

$ sudo ls -al /vz/private/164/etc/rc.d/rc.local
-rwxr-xr-x 1 root root 227 Jun 25 20:17 /vz/private/164/etc/rc.d/rc.local

Whereas the same command (i.e. echo "# oneadmin test" >> 
/vz/private/164/etc/rc.d/rc.local) is performed normally under superuser.

CT is based on Scientific Linux 5 template. Hardware node is running 
under CentOS 5.6.

Does someone have any ideas what can be the reason of insufficient 
privileges for regular user with full root rights granted via sudo?

Thanks in advance,
Nikolay.
