Preserving Hosts File Edits for Roving Edge Infrastructure

Preserve your edits to the /etc/hosts file on a compute instance on your Roving Edge Infrastructure device.

To preserve your edits to the /etc/hosts file on a compute instance in Roving Edge Infrastructure, open the following file:

/etc/oci-hostname.conf

Update the PRESERVE_HOSTINFO value at the bottom of the configuration from the default 0 to 2 or 3. For example:

# This configuration file controls the hostname persistence behavior for Oracle Linux
# compute instance on Oracle Cloud Infrastructure (formerly Baremetal Cloud Services)
# Set PRESERVE_HOSTINFO to one of the following values
#   0 -- default behavior to update hostname, /etc/hosts and /etc/resolv.conf to 
#        reflect the hostname set during instance creation from the metadata service
#   1 -- preserve user configured hostname across reboots; update /etc/hosts and 
#           /etc/resolv.conf from the metadata service  
#   2 -- preserve user configured hostname across instance reboots; no custom  
#        changes to /etc/hosts and /etc/resolv.conf from the metadata service,
#        but dhclient will still overwrite /etc/resolv.conf
#   3 -- preserve hostname and /etc/hosts entries across instance reboots; 
#        update /etc/resolv.conf from instance metadata service
PRESERVE_HOSTINFO=2

Updating the PRESERVE_HOSTINFO value prevents the metadata service from overwriting the changes to the /etc/hosts file.
