LinuxQuestions.org - [SOLVED] starting BLFS when finished LFS in Slackware & Please help me!

Okay. So I saw your post in the Slackware forum. It's trying to boot now. I don't want to post over there. But I recommend against that guy's idea to create an initial ramdisk for drivers. That is possible (there is a hint article about it), but the classic LFS way to handle that is by building in things that the kernel needs to boot. And today one guy over there referred you to the v6.5 LFS book as the newest version. Uh, maybe we should continue on here until you need Slackware boot loader help again.

The kernel is loading and starting its message spew, then stops very early. I recommend that you review your kernel config for file system and storage device support at this point. And it should be built in (* or =y), not modules (M or =m). That is the kind of stuff that can stop it from booting early. Another common error these days (I made it, too) is to forget to build in support for devtmpfs. Your LFS system will not boot without that. Not everything has to be built in. I have lots of modules, too. But this stuff needed for booting has to be built in.

Here, only as an example of what I mean, are some snippets from my kernel menuconfig notes regarding these kinds of filesystem and storage device things. I don't mean for you to mindlessly copy this stuff. Just review yours and make sure it accommodates your filesystem and hardware. A good idea for the hardware stuff is to examine the drivers in use by your host system, then see to it that the ones needed before the filesystem is mounted are built in to your LFS kernel...

And if you get past this stuff, it may not be over. Brace for more of it that may need work after it boots. I spent days on video driver and firmware issues. I probably recompiled my first LFS kernel thirty times (not joking about that). I don't mean to sound discouraging, but there's no use in pretending at this point either.

P.S.: No promises for any of this. You may have a lot more work to do. But that stuff you're getting in the Slackware forum today will just have you wandering off into the tall weeds. I promise you that.
