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.
It's the same set of files as for each kernel.
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"?)
Give the /boot partition at least 1GB or maybe more since you want 5
kernels. The default is 1GB. Another alternative is to not create a
/boot partition and let it be part of /. Unfortunately, the new
installer is more limited and if you change from the default, you have
to do everything yourself. But in that case, it would only be two
partitions you need to make.
The new desktop has:
* 1 TB M.2(?) NVMe(?) drive for the operating system and installed
applications, and
Do you think you're going to have more data than will fit on this? It
would be a huge waste to just have the OS on there.
* 4 TB spindle drive for personal stuff.
If you really need this, I would recommend mounting this somewhere for
data storage or better, format it as btrfs and mount subvolumes as needed.
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.
You'll need to adjust the setting in /etc/dnf/dnf.conf as mentioned
previously.
