GRUB2 in Slackware? Discussion and Instruction.

colorpurple21859 · 08-16-2023, 05:28 AM

I would like to be asked to update the grub.cfg , or have the option to disable auto-updating of the grub.cfg with kernel upgrades.

Anyway, all that is moot. I'm not against auto-generation of initrd on a kernel package install/update (My slackup util even comes with support for running post-install scripts and an example script which does exactly this). What I'm against is triggering the action from within doinst.sh.

See I don't think that is really true or ever was. First SLS and then Slackware, were by their very definition about automation, being able to install and setup a running system without having to build a filesystem on some other host first. Slackware has always done a lot of stuff FOR you like configuring LILO, setting up network, making it somewhat easy to turn on and off daemons etc.

What it has avoided ever doing was trying to prevent you from modifying the system in anyway you like, or doing anything surprising like undoing your changes because "it knows better", or trying to 'adapt' on the fly - ie oh hey you added a new NIC so lets blow away the configuration you had from the other ones, because nobody ever connects up hardware to test something quick we always want to completely reconfigure the host right right? Finally its usually understandable where things are coming from and what is behind them, ie shell scripts you can go read, rather than binary blobs.

Any I think Slackware isn't about not automating, it is about not over-automating, and it should handle nominal use cases out of the box without excess fuss. I think that includes installing the boot loader and keeping it coherent across official kernel package updates (including during current). If it also handles custom kernels nicely, well that is better as long as it does not become to complex to understand and ration about what is going to happen easily.

If you truly want hands on - there is LFS.

With all respect, the Slackware arrived to become a niche Linux distribution from a mainstream position.

And I am afraid that it become "a niche Linux distribution" by having unpredictable release dates and delivering features always too late. And by questionable decisions like the removal of GNOME, transforming LinuxPAM and/or PulseAudio on "controversial issues" when everybody used them, by not shipping NGINX or whatever features the server guys needed, and even by making a release on KDE4 when everybody else already showed up the Plasma5. And yes, playing Jihad with ConsoleKit2 certainly does not helped much. Or the requirement to manually intervention on system boot and shipping obsolete bootloaders by default.

Now excuse me, Mr. GAZL, but Slackware hasn't been a niche Linux distro, but had become one because the majority of the Slackware users ran away. You can blame me, but I dream about some of them to return back...

I believe that you can (and should be able to) play your "hands-on" with Slackware as you wish, but Slackware should deliver some robust default features for the system boot.

with all respect, this is a well tested and proved way (by all those today mainstream distros) to handle this system boot features, and if you are against it, just don't use it.

You can continue to do everything by hand, as you like. I strive to ensure that you can be always able to do this.

BUT, the adding this features support to installpkg/upgradepkg (or whatever else) script will not work always, because you will need to hard code the packages name to which them will be available. And an example against was said by a friend of mine: some people may need to include in initrd proprietary modules for certain storage hardware (i.e. RAID cards) . And yes, there's DKMS to automate the building the kernel modules, BUT how you update your initrd when you install/upgrade a random package?

Back to grub on a uefi motherboard with a fairly fresh install of slackware-current

I have a elilo working swell. I've installed grub, but it will not boot.

If I boot from the slackware cd and select boot any operating system, it shows both elilo and grub. If I select grub, the screen flashes for an instant and then returns with the grub screen, now showing just slackware, no grub.

I'd like to get grub running... I'm also reading that a new version of grub is now in beta release, which makes me wonder if the grub in -current is on the broken side.

You are kind to explain how you installed the GRUB2 on your UEFI mode? I for one, I have never hit a case where ELILO works but GRUB2 doesn't.

And would be very useful also to show us your /boot/grub/grub.cfg.

Anyway, please note that if you install the GRUB2 from installer system, you need to bind /dev, /proc and /sys on target system (mounted on /mnt) by using mkbindmounts or manually, then you should chroot to /mnt and to mount also the /boot/efi.

You may just boot your system with ELILO, then to mount (if not is mounted yet) the ESP, usually this /boot/efi.

Finally, from there you call the the grub-install. Failing to make any of these steps will end in a failure on installing GRUB2.

Yeah, this means manually installing GRUB2, and hopefully in the future we will have that grubconfig about we talk about, to make these steps for us.

You are not alone.
What is that old saying? Something along the line of, "They will have to pry it out of my cold, dead hands."

That's great! But, HOW you installed the GRUB2 bootloader? With which command(s) ?

Also, I would like to known the output of the command:

Code:

efibootmgr

Again, do you mounted the /boot/efi before executing these commands?

And another question: do you are sure that your motherboard accept to run /EFI/BOOT/BOOTX64.EFI ? Some motherboards doesn't.

I ask this because the option --removable will put in this place the EFI binary for GRUB2.

And AGAIN: Please use the [code] tags to wrap you output or files content, to me be able to read what you wrote.

I ask about something like this:

Yes, /boot/efi was mounted.

my ESP looks like this:

(I've tried a lot of things ;-) )

I can boot from the slackware cd, so yes, BOOTX64.EFI works on this machine.

And what do you means 'tags?'

Yep, I have seen this.

First of all, please remove any references to GRUB2 on efibootmgr - this mean executing something like this:

Code:

efibootmgr -q -B -b 0001

BIG FAT WARNING: be careful at the numerical parameter, you risk to broke your boot, i.e. you ELILO.

Then, please try the following command from the target system (NOT from Slackware installer) with /boot/efi mounted.

Code:

grub-install --target=x86_64-efi --efi-directory=/boot/efi --bootloader-id=GRUB --recheck

Then please show me the output of this command.

Some UEFI motherboards accepts to boot from an external drive using the path /EFI/BOOT/BOOTX64.EFI, while NOT accepting the same path for an internal hard drive. Even my self I have several motherboards which has this behavior.

So, the fact that you can boot from Slackware CD does NOT mean that the path /EFI/BOOT/BOOTX64.EFI works also for your internal hard drive.

Please read carefully the documentation from the link bellow, before posting anything else. To express in a readable mode I believe is the first step to ask for help.

Please forget about /EFI/BOOT/BOOTX64.EFI; right now that's a red herring. It's the grub entry that I'm concerned about.

I'll read your bit and continue to post.

Thank God no need to change bootloader. I am staying with elilo as it works on my notebook so no reason to switch to grub.
While I understand the move, I aslo think that lilo/elilo should stay as grub has enough issues on its own.
