I would like to use Oracle Linux 6.4 (64 bit). This is a RHEL based disto, very similar in process/licensing with CentOS 6.4
I suspect that even if that conversion script works (and it looks simple enough), you wouldn't get the arguably-most-important benefit of Oracle Linux, their "unbreakable" kernel. DO's hypervisor doesn't (AFAIK) allow droplets to run arbitrary kernels.
It would be very useful to have Oracle Linux as a droplet option. It is almost identical to CentOS and is also free, but it is supported by Oracle if you want to run their database.
I also tried the script provided by Oracle to convert CentOS to OL (https://linux.oracle.com/switch/centos/) but it failed and left the system unstable. Be sure to have a backup or make an image of your Droplet before you try this on DO. Oracle Support knowledge base wasn't useful either "Issue With Centos2ol.sh (Doc ID 1527385.1)" as I found additional problems with the script, such as accessing invalid pages at poptop.sourceforge.net
You can try the following link to convert CentOS to Oracle Linux.
I'm also interested in this.
You won't be notified about changes to this idea.
