initrd.img doesn't point to the newly (and newer) installed kernel

I'm on Ubuntu 20.04.

I was on 5.8.16-050816-generic, this kernel version was installed by downloading from Ubuntu's mainline.

Just recently, I manually build kernel 5.14.0-next-20210913+ grabbed from upstream linux-next tree. I did update initrd, and grub. But one thing I notice and curious. Why initrd.img still points to the old kernel version, but vmlinuz points to the newest one. See below.

What might be the issue? Is it safe for me to manually re-link symlink of initrd.img myself to point to the correct one?

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
