apt-get upgrade via ssh y vzctl
Buenas Listeros,
Tengo varios servidores con varios containers openvz corriendo en cada
uno. Para actualizar el sistema a través del apt uso un script que se
connecta al servidor fisico por ssh y lanza el "apt-get upgrade" a
través de la herramienta vzctl. así:
ssh root@"$node" -C "vzctl exec $vmid \"$action\"
node: servidor físico
vmid: identificador del container
action: apt-get upgrade
pero haciendolo de esta forma me encuentro con problemas cuando en
algunos upgrades aparece el dialogo preguntando algunas cosas. En ese
momento creo que es cuando me aparece el siguiente error de debconf:
The following packages will be upgraded:
libmysqlclient15off mysql-client mysql-client-5.0 mysql-common
4 upgraded, 0 newly installed, 0 to remove and 2 not upgraded.
Need to get 0B/10.2MB of archives.
After this operation, 147kB of additional disk space will be used.
Do you want to continue [Y/n]?

Alguna idea de como evitarlo? se puede redirigir el dialogo hacia la
tty donde ejecuto el script?
