OpenCloud package hidden

[girish]

When writing tests for the package, I found that restoring OpenCloud from a backup loses data.

It turns out this is becase OpenCloud requires a filesystem with extended filesystem attributes . Cloudron's backup system does not save/restore xattrs. This is confirmed in this comment upstream .

I have made this package hidden since it will result in data loss (even though this was only in unstable to start with).

Just a generate note, in case you run this outside Cloudron - this also mean that the app is not compatible with a) filesystems which don't have xattr and b) backup systems such as rclone (issue) and others. Looks like borg and restic support it, but I haven't tested it myself
