Hello,
I've just finished setting up an x86_64 LFS installation on a flash
drive. I have followed the LFS 9.0 book almost exactly, except that I
upgraded the kernel to 5.2.21, and I'm using UEFI instead of BIOS for
GRUB using the hint given in Chapter 8.4. To test the new setup, I ran
a QEMU VM using the OVMF EFI, booting from the drive via -hda. It
worked fine, booting to the Bash prompt and everything. I then tested
the installation on real hardware, but the kernel panicked saying it
couldn't find init. But even after setting init=/sbin/init, Linux
still panicked saying "Requested init /sbin/init failed (error -2)". I
have tried reinstalling sysvinit to no avail, and I have been unable
to reproduce the issue in any VM (QEMU, VirtualBox). Loading the
kernel manually in QEMU (-kernel) works too, which bypasses the UEFI
entirely. I've also tried using different computers, but they still
have the same problem. Does anybody have any idea why this may be
happening?
Hi Jack,
It seems that you're getting your system to initialize the kernel, so
that's a good sign. At this point, this normally leads to a driver
problem (although I only have legacy systems, I have UEFI/secure boot
disabled on my newer equipment). I'm assuming that you have another
distro on your real hardware, but if you don't, you can boot something
like SystemRescueCD off a CD or USB drive to check this. At a terminal,
execute the following:
lspci -vv | grep driver
The next thing you're going to want to do is run 'make menuconfig' in
your kernel sources, and then press the "/" key (shortcut for "Find"),
and type in the name of each driver (it'll be in the output of "kernel
driver in use:"). Make sure that each one is enabled (built in, not
modules), especially the driver for your SATA controller.
After that, make sure that you have the proper filesystem support built
in. I know you've got it to boot in a VM though, so I'm sure this is
redundant, but it's important to make sure it's enabled anyway :-)
