Success! I've managed to boot LFS 8.0, X Windows, Firefox and Thunderbird. I've learned a lot about Linux from this, especially how to boot with an EFI bios and GTP partitions.

It used to be horrendous to configure. I run postfix, which provides /usr/sbin/sendmail. I looked into installing that, but on first glance it looks like a lot of work configuring it. Comments? Now that Thunderbird is working, do I need Postfix? Just mentioning that in case it is something in sendmail that is hanging. Turns out sendmail was working ok. But I've disabled it. The computer itself quits working -- I have to turn the power switch off and on to reboot to the host system. A bit more clarification: Normally when Grub starts, the screen goes blank for a few seconds, the mouse and keyboard lights turn off (I have an illuminated Logitech keyboard), and after a few seconds it all turns back on, and you get the Linux startup messages. In my case, everything went blank, and never turned on again. That's why I had to power cycle the power supply. 1. My thought process on trying to debug this With traditional sysvinit, the kernel has invoked init and that has gone into your chosen runlevel (probably runlevel 3?). I suggest that you begin by looking at the bootscript for sendmail, to see if it starts multiple programs. If it does, try adding messages between them. I looked at several useful bootlog files in /var/log: boot.log kern.log sys.log These showed that sendmail was working, along with some potential gotchas. Alternatively, if sendmail really is running ok then the problem would be with the *next* script (ordered by the SNN symlink numbers). But if that next script begins to execute, I would expect it to report something. So this sounds to me as if sendmail is not completing. I ended up disabling all of the stuff that is started by scripts in blfs-bootscripts. The log files indicated no problems except for the NIC related stuff, which I eventually sorted out. If you have enabled MagicSysRQ in your kernel, and your keyboard has a SysRq key (possibly on PrtScr - labels may differ slightly), you can probably force a reboot. For my desktops I think I use AltGr e(right Alt) and PrintScreen - hit the magic key combination for your keyboard, followed by s (sync), wait briefly, then use the magic key combination followed by b (boot) or, at the end of the session o (off). These will do unclean shutdowns, so next boot will fsck, but the Sync will update logs, particularly the system log and maybe the mail log, boot log (boot log tends to be not very informative). If you didn't enable that in your kernel config, wait a few minutes so that the logs have hopefully sync'd. None of the above could work, since the keyboard and mouse were powered off, and the computer hung. 2. Recommendations, now you know how I've got them: As a first stage, from the host look at the LFS logs to see if there is anything useful. If there isn't, as root chmod 644 /mnt/lfs/etc/rc.d/init.d/sendmail so that you can read and edit it but it will not automatically run. If you are able to boot without sendmail, you should have a working keyboard on several ttys : from one of those, root can try starting sendmail, or just stepping through the invocation(s) in that bootscript [ i.e. run commands directly ]. Alternatively, and if you have NOT booted this system in LFS before you added the extra packages, perhaps you did not build the (correct) keyboard driver (usb and PS/2 might be different, I'm not sure). Following the above advice, and that from another email, I did this: Fixed the various NIC settings (ifconfig, etc.). Added all of the CONFIG settings I thought were applicable to the Kernel. Recompiled the kernel. Disabled all of the blfs-bootscripts startup scripts. Magically, a reboot worked and I got a login prompt. Then I reversed all the disabling, one step at a time, and everything continued to work. Finally I installed a bunch more BLFS stuff, X Windows, etc. Thanks for the help!

[lfs-support] Booting from EFI Hints
Since yesterday, I installed quite a bit more BLFS software, plus the rEFInd boot manager from RodsBooks. Sendmail is now installed. LFS seems to boot up to the "komodo login:" prompt, and then hangs. Every kernel message shows [ OK ] on the right side of the screen. The last is for "Starting sendmail". The NIC seems to come alive. So at this point, I can boot using two methods: Grub, which loads vmlinuz-4.9.9-lfs-8.0 rEFInd, which loads grub, which loads vmlinuz-4.9.9-lfs-8.0 Each of the two methods results in the same kernel startup messages and then a hang. It's as if something is wrong with the vmlinuz image. I tried the EFI stub loader method but probably didn't do it properly. Ideas?

So far, I've gone with the assumption to install to /dev/sdd, apparently successfully. But see below. Also, I have five disks installed, all running and all with different Linuxes in various states, so I have to be very careful keeping track of which disk is which. >> 2.

Ok, here is the new one, after converting to GPT using gdisk: /dev/sdd4 /ext4defaults1 1 /dev/sdd1 /boot/efivfatdefaults0 1 /dev/sdd3 /bootext4defaults1 2 efivarfs /sys/firmware/efi/efivars efivarfs defaults 01 /dev/sdd5 /opt ext4defaults1 2 /dev/sdd6 /homeext4defaults1 2 /dev/sdd2 swap swappri=1 0 0 > Personally, I long-ago stopped giving /opt its own filesystem: if > '/' is big enough, I can rename directories in /opt for testing a > newer version.

Payment is perhaps the satisfaction of a job well done.

My personal opinion > of UEFI is still "There be dragons." That's for sure! On this new machine of mine, I've disabled Secure Boot (had to remove a Key) but I'm using UEFI boot, since disabling it means enabling the old CSM Legacy boot in the Bios. > I suspect I might have to learn more about it for my next machine. I don't think we will have much choice, given that the industry is going that way. I'm thinking that in the long term, I might try installing LFS with Secure Boot, ala the material in RodsBooks. The lfs-uefi.txt hint mentions this as a good resource. > No timescale for that, I started using gimp-2.9 on my photo-editing > machine and discovered it was underpowered (2.9 seemed to only use 1 > core, and the xcf files are a lot bigger) - but meanwhile I'm using > 2.8 on my development machine and that is ok.

Already been there. Grub trashed my Fedora boot partition when I used it wrongly first time around. Apparently I messed up sending the above yesterday, so here it is again. Sorry if it's a duplicate.

My personal opinion of UEFI is still "There be dragons." I agree. I do not know of any reason to use secure boot or uefi (they are separate) unless you want to dual boot to windows. That's verbotten here.

If you ever want to use that to build a newer / second-attempt LFS on the same disk, you will also need a spare partition for the new system.

I don't know for certain, but I suspect most of the editors have been able to disable UEFI on new machines. My personal opinion of UEFI is still "There be dragons." I suspect I might have to learn more about it for my next machine. No timescale for that, I started using gimp-2.9 on my photo-editing machine and discovered it was underpowered (2.9 seemed to only use 1 core, and the xcf files are a lot bigger) - but meanwhile I'm using 2.8 on my development machine and that is ok.

[lfs-support] Booting from EFI Hints
Following the advice of akhiezer in his note from 18-May-2017, I'm going back to try to install LFS stable version 8.0, in order to gradually work up to installing LFS systemd development version with LVM, LABEL/UUID in fstab, intramfs, etc. However, I'm getting conceptually stuck at how to boot with my EFI motherboard (Asus TUF Mark 1), using the lfs-uefi.txt hint mentioned in the LFS book, ch. 8.4.1. Note that my host Fedora is on /dev/sda, and I'm putting LFS on /dev/sdd. Other hard disks contain incomplete experiments, with /dev/sdc containing an incomplete systemd. >From the lfs-uefi.txt hint in LFS book, ch. 8.4.1 at # http://www.linuxfromscratch.org/hints/downloads/files/lfs-uefi.txt MOUNT EFI PARTITION Determine which device is the EFI partition using gdisk or parted, enter the chroot environment, create /boot/efi if needed, and mount -vt vfat /dev/sda(x) /boot/efi where sda(x) is the device containing the EFI partition. Two sticking points: 1. I assume that with my present setup, I should use /dev/sdd rather than /dev/sda, because I DON'T want to change the Fedora boot stuff. Rather, I want to be able to boot directly from the LFS disk. Ultimately, I want to use a boot manage like RodsBooks' rEFTnd (which I successfully installed on /dev/sdb). And if I remove all disks, but /dev/sdd, I want to boot directly from that. 2. Do I use the LFS book's instructions on partitioning a strictly MBR boot setup, or make GPT partitions? See the information and discussion below. To let you see my setup, I've gotten some info on my setup from various disk commands. The difference between a stricly MBR partition scheme and a GPT scheme can be seen in the outputs from the following info commands, executed in the LFS chroot or Fedora host environment as needed. Note that I'm inserting some comments for clarification: # In LFS chroot: ## root:/sources# lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT ... # Development Version 20170518-systemd sdc 8:32 0 1.8T 0 disk |-sdc1 8:33 0 1G 0 part |-sdc2 8:34 032G 0 part |-sdc3 8:35 0 1G 0 part |-sdc4 8:36 0 200G 0 part |-sdc5 8:37 0 200G 0 part `-sdc6 8:38 0 500G 0 part # Stable Version 8.0 sdd 8:48 0 931.5G 0 disk |-sdd1 8:49 0 1G 0 part /boot |-sdd2 8:50 032G 0 part [SWAP] |-sdd3 8:51 0 200G 0 part / |-sdd4 8:52 0 1K 0 part |-sdd5 8:53 0 200G 0 part /opt `-sdd6 8:54 0 498.5G 0 part /home ... ## # In LFS chroot: ## root:/sources# fdisk -l /dev/sdc Disk /dev/sdc: 1.8 TiB, 2000398934016 bytes, 3907029168 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disklabel type: gpt Disk identifier: 758C423C-3C5D-472B-92C3-ACB1B2026A7A Device StartEndSectors Size Type /dev/sdc1 2048209919920971521G EFI System /dev/sdc22099200 69208063 67108864 32G Linux swap /dev/sdc3 69208064 7130521520971521G Linux filesystem /dev/sdc4 71305216 490735615 419430400 200G Linux filesystem /dev/sdc5 490735616 910166015 419430400 200G Linux filesystem /dev/sdc6 910166016 1958742015 1048576000 500G Linux filesystem ## ## root:/sources# fdisk -l /dev/sdd Disk /dev/sdd: 931.5 GiB, 1000204886016 bytes, 1953525168 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disklabel type: dos Disk identifier: 0x66f87996 Device Boot StartEndSectors Size Id Type /dev/sdd1 * 204820991992097152 1G 83 Linux /dev/sdd2 2099200 69208063 6710886432G 82 Linux swap / Solaris /dev/sdd369208064 488638463 419430400 200G 83 Linux /dev/sdd4 488638464 1953525167 1464886704 698.5G 5 Extended /dev/sdd5 488640512 908070911 419430400 200G 83 Linux /dev/sdd6 908072960 1953525134 1045452175 498.5G 83 Linux ## # On Fedora host: ## [root@localhost alan]# gdisk -l /dev/sdc GPT fdisk (gdisk) version 1.0.1 Partition table scan: MBR: protective BSD: not present APM: not present GPT: present Found valid GPT with protective MBR; using GPT.
