Looking more closely at the script, it's just issuing "ipset save" and dumping the output into /etc/sysconfig/ipset, after backing up any previous configuration. So it's easy enough to just do that and ignore the script. Curiously, the start() function in the script doesn't load the ipset module or check that it's loaded. Only the stop() and save() functions check. Seems inconsistent. I'll have to ask the package maintainer why they're doing it that way. Meanwhile I bit the bullet and switched to the stock CentOS 7 kernel by selecting GRUB2 from the Linode boot menu. It took a few reboots to get it right. It had to relabel the filesystem as the Linode kernel lacks SELinux and I had to run the utility to rebuild the GRUB menu. (Linode had already written its required modifications to the GRUB config files.) https://www.linode.com/docs/platform/manager/how-to-change-your-linodes-kernel/
