I renamed this thread since I've chosen to not make the new desktop dual-boot.

Good thing I asked.
Thank-you, Samuel.

By default, how does Fedora handle rescue kernels?

By default they aren't updated unless you delete the old one. I don't know how you would change that.

There are two obvious ways: rename it or move it to a different directory.

That's not what I meant.  That's what I said about deleting it. But I don't know that there's any way to change the default to have it update automatically.  I don't think that would really be a good idea anyway.

Does the rescue consist of only one file?  If not, renaming and moving are not so simple.

On to the real question...

I know a few people have encountered running out of storage space when a kernel gets patched or upgraded.  It happened to me a few times.  I recall seeing somewhere that this can be avoided with wise partitioning, which is a part of installation.  I also recall seeing that kernels have grown quite a lot over the years.   (Hmmm...  Is someone feeding them too much fructose and other "refined carbs"?)

The new desktop has:
* 1 TB M.2(?) NVMe(?) drive for the operating system and installed applications, and
* 4 TB spindle drive for personal stuff.
Assume that I want most things stored uncompressed and unencrypted.
Assume that in addition to the kernel, I'd like to keep 5 old kernels + a rescue. I, of course, want to have lots of space available for kernel growth over the next decade.
How should I partition the drives?
