I'm using Fedora 24. Whenever I update the kernel, Fedora saves the two previous entries as backups, in case something goes wrong with the update.I want to try to compile the kernel on my own (I want to enable ipv6 subtrees), and I would like the newly compiled kernel to be in a separate entry, not overwriting any of the fedora entries.I tried to make five entries by setting installonly_limit=5 in /etc/dnf/dnf.conf, and I upgraded the kernel, but on reboot I still only see 3 entries, not 5. (Actually there are 6, 3 Fedora, 1 fedora recovery(?) and 2 windows. But I would like 5 for Fedora.)Do I need to change anything else? Will compiling a new kernel overwrite any previous entries or will it just add an entry?
