On fedora config file is on /boot

Thanks for reporting it. Just to double-check, do you have any /proc/config* files at your system?

anatol · 2022-02-28T02:50:37Z

Could you please also provide output of ls /boot/?

Booster reads kernel's config file at generation time. Some systems (e.g. Arch Linux) provides /proc/config file. Some other systems (e.g. Fedora) have /boot/config-$kernelVersion. Add support for the /boot config path. Implements #137

@arun54321 I added a change that implements this /boot/config-* feature. Please check wip branch and let me know if it makes any difference for you.

What go version do you use?

arun54321 · 2022-03-01T03:01:50Z

go version go1.16.14 linux/amd64
I installed it from fedora repos.

I will try again after updating to 1.17.7

anatol · 2022-03-01T03:02:59Z

I believe clevis.go has been go mod tidy with 1.17 compat.

Does Fedora provide 1.17 go? If not then I will need to downgrade modules to 1.16.

anatol · 2022-03-01T22:06:56Z

@arun54321 let me know if you was able to get it compiled with 1.17.

arun54321 · 2022-03-02T02:08:54Z

I have compiled v1.18 . Does it compile on that?

anatol · 2022-03-02T03:01:51Z

Yes, it should work with 1.17+.

arun54321 · 2022-03-02T10:47:14Z

I don't see the error now. so I think it is working now.

But booster from this branch does not create initramfs image.

anatol · 2022-03-02T18:17:17Z

Booster fails for some reason:

enabling virtual console

I need to look at the code to figure out why there is no any error message for this failure.

Also related question. Is golang 1.17 easily available for Fedore users? Is it ok to use 1.17 specific feature or it is going to be a lot of troubles for Fedora users?

Related #137

anatol · 2022-03-02T19:18:04Z

My guess that there is a problem with loadkeys binary. I added a commit that prints more information in case of its failure. @arun54321 please pull the changes from wip and try it one more time. Share your debug output as well.

You can also disable vconsole option in your config file to skip this step.

thanks. What is the content of /etc/vconsole.conf and /etc/locale.conf?

what is output of loadkeys -q -b us?

I'm using fedora for around a week or 10 days. I don't know about fedora release schedules. For a time being anyone could use my copr repo till it arrives on official repositories.

1.18 is coming in fedora 36 so It should not be problem in future.

It looks like this in terminal.

If loadkeys -q -b us works for you then I don't really understand why booster with the same command.

Could you please post output of /etc/booster.yaml? And btw you can paste the text right here, without using screenshots.

strace.zip

anatol · 2022-03-04T20:09:13Z

Looking at strace output I see that loadkeys called with correct parameters:

execve("/usr/bin/loadkeys", ["loadkeys", "-q", "-b", "\"us\""], 0xc000d05440 /* 68 vars */ <unfinished ...>

(which is loadkeys -q -b "us")

yet it fails with

[pid 12157] write(2, "loadkeys: ", 10)  = 10
[pid 12157] write(2, "Unable to open file: \"us\": No su"..., 52 <unfinished ...>
[pid 12157] <... write resumed>)        = 52

it is not clear for me why it happens. It might be that Fedora's loadkeys expects some env var or maybe something else.

arun54321 · 2022-03-05T03:38:07Z

Could you look at fedora's kbd patches?

https://kojipkgs.fedoraproject.org//packages/kbd/2.4.0/8.fc35/src/kbd-2.4.0-8.fc35.src.rpm

Some users add quotes around property values in these files. Strip the quotes to avoid `loadkeys` tool confusion. Related #137

anatol · 2022-03-05T07:59:09Z

@arun54321 I actually found one more difference from my setup. The values in your /etc/vconsole.conf have quotes around values (KEYMAP="us"). I added code that strips these quotes. Hopefully it fixes the problem with loadkeys. Please take a look at wip branch.

arun54321 · 2022-03-05T10:04:16Z

I tried to symlink libc file to the destination.
Now I get open /usr/share/kbd/consolefonts/: no such file or directory

On fedora that folder is in /usr/lib/kbd/consolefonts

Image generation is working now after symlink those missing folders.

Fedora keeps some of its libraries under /usr/lib64. Look at this directory when searching for ELF libraries. Related #137

anatol · 2022-03-05T16:54:35Z

libc file is in /usr/lib64. How do I compile / fix it properly?

I added /usr/lib64 path to the booster search list. Booster wip should work for you now without any extra symlinks.

Different systems have different consolefonts path, e.g. Fedora uses `/usr/lib/kbd/consolefonts`. Having this path as a separate constant makes it easier to patch for a specific distro. Related #137

anatol · 2022-03-05T17:09:45Z

On fedora that folder is in /usr/lib/kbd/consolefonts

I added a patch that makes it easier to configure this folder. Distros could update this path if needed.

So the fedora package should patch booster path to /usr/lib/kbd/consolefonts

anatol · 2022-03-05T17:14:01Z

Image generation is working now after symlink those missing folders.

Could you please pull wip branch, remove all the symlinks you've made and then try booster one more time?

anatol · 2022-03-05T17:14:49Z

open /usr/share/kbd/consolefonts/: no such file or directory

The sourcecode needs to be patched to adjust it to Fedora's defaults.

arun54321 · 2022-03-05T17:14:54Z

Should I apply the patch or just pull and build again?
edit: ok

arun54321 · 2022-03-05T17:20:55Z

Works well.

anatol · 2022-03-05T17:26:24Z

Could you please also make a package for Fedora so other people can use the package easily? Is there any way to get this package to Fedora repository?

Could you add force and kernelVersion flags to wip branch?

I am trying to write image generation script. It doesn't work due to missing flags.

So far, it works without those flags.

#!/bin/bash -e

# find out all installed kernels
kernels=($(rpm -q kernel-core))

for kernel in "$kernels"; do
    version=$( echo $kernel | sed 's/kernel-core-//g' )
# write to tmp for testing
    booster  build /tmp/booster-${version}.img  &
done

wait

It outputs

unknown flag `k'
unknown flag `f'

anatol · 2022-03-11T15:25:01Z

The flags start with double hype: --force. Please see man page for more information.

arun54321 · 2022-03-11T16:24:41Z

tmp ❯ booster --force build /tmp/booster.img
unknown flag `force'

anatol · 2022-03-11T17:10:02Z

--force and --kernel-version are build subcommand flags. i.e. you have to put it after the build codeword.

Here is an example of usage https://github.com/anatol/booster/blob/master/packaging/arch/regenerate_images

arun54321 · 2022-03-11T17:16:56Z

Thanks. Works fine now.

#!/bin/bash -e

# find out all installed kernels
kernels=($(rpm -q kernel-core))

for kernel in "$kernels"; do
    version=$( echo $kernel | sed 's/kernel-core-//g' )
# write to tmp for testing
    booster  build --force --kernel-version ${version} /tmp/booster-${version}.img   &
