Can I hardlink config files?

[Dennis Kaplan]

I have this idea to ease administration of my lxc virtual boxes by hard linking some of the configurations files, like sshd, fail2ban etc. I am the only one with root access to the boxes!

• Will the files only change if I change them in the physical server, or can they be modified from every virtual box? I am thinking that I will be able to modify them from any of the servers.
• Are there any other implications I am not thinking of?
• I am guessing soft links ln -s won't work?
• Does the command below look okay?

From the physical server:

rm /var/lib/lxc/vm0/rootfs/etc/ssh/sshd_config
rm /var/lib/lxc/vm1/rootfs/etc/ssh/sshd_config
rm /var/lib/lxc/vm2/rootfs/etc/ssh/sshd_config
rm /var/lib/lxc/vm3/rootfs/etc/ssh/sshd_config
ln -p  /etc/ssh/sshd_config /var/lib/lxc/vm0/rootfs/etc/ssh/sshd_config
ln -p  /etc/ssh/sshd_config /var/lib/lxc/vm1/rootfs/etc/ssh/sshd_config
ln -p  /etc/ssh/sshd_config /var/lib/lxc/vm2/rootfs/etc/ssh/sshd_config
ln -p  /etc/ssh/sshd_config /var/lib/lxc/vm3/rootfs/etc/ssh/sshd_config
