Hello again,
after a discussion on #centos-devel, I'm writing down here the
way we create our 'system' CentOS image for Synnefo:
[Quoting from our internal wiki]
--- cut here ---
CentOS is a basic (minimal) CentOS 6.5 system which was created using
the netinstall CD (CentOS-6.5-x86_64-netinstall.iso).
Extra configuration:
1.Full update
yum update
yum upgrade
2.Install and start acpid
yum install acpid
service acpid start
chkconfig acpid on
3.Clean the yum cache
yum clean all
4.Remove the HWADDR line from /etc/sysconfig/network-scripts/ifcfg-eth0
5.Delete udev rule for persistent nic names
rm /etc/udev/rules.d/70-persistent-net.rules
6.Install and run ntp deamon
yum install ntp
chkconfig ntpd on
In /etc/ntp.conf put the servers of a specific zone
7.Disable time dependent file system checking
tune2fs -i 0 /dev/vda1
8.Install network manager
yum install NetworkManager
9.Allow DHCPv6 responses in the firewall
10.Unhide the GRUB menu, by commenting out the hiddenmenu option in
/etc/grub/menu.lst

After the above steps, the image is ready to get spawned on
any Synnefo deployment and will get customized automatically.
So, do you think it is possible for you guys to have such an
'official' CentOS image targeted for Synnefo?
Thanks,
Constantinos
