How do packages and the kernel update in Linux LFS?

Question

linux

I thought of a scam - to make LFS for my netbook (Linux From Scratch - if anyone doesn't know, it's to build Linux for a specific machine, and not use a ready-made distribution kit)
And then the assemblies and derivatives are something very weighty and completely slow down the netbook
Tell me how in the end it will be possible to update? With distributions and derivatives, it is clear there - rolling or version is being updated, but what about in this case?

Answer 1

if you ask such questions, then you should not even touch such things at all.
There will be two questions for you, the first: - "What did Gentoo not suit you for?" if you can just use simpler things?". It just all seems very strange to me.

Answer 2

So you need a package manager, build everything with it, and not install through make install. This raises the complexity by an order of magnitude. Therefore, they write to you about ready-made distributions. I guess LFS is a toy to understand how it works, what it interacts with and so on. This is not what they put as the main system, because in addition to what is started and running, you need a bunch of other infrastructure things. Installing the same browser will be an order of magnitude more difficult, since in addition to the browser itself, all dependencies will need to be provided, which is not so easy without a package manager.

Answer 3

Same as installation. wget, tar -xvf, ./configure, make, make install, basically.
