Using pacman as the package manager
 
Hi,

I was debating on which package manager to use for my LFS build. I used Slackware's package manager successfully but I couldn't get Arch Linux's Pacman to work. I followed this guide for Pacman on LFS 8.1 (modified it for LFS version 9.0) but as it was mentioned in the guide "... many binaries and other files were owned by ben," which is where I also got stuck on. It was fixed by manually changing owner on those files mentioned but I don't want to be doing this every time I build and install a package.

Any suggestions on how to fix this problem of having the incorrect owner on the libraries, binaries, etc.? I tried searching for a reason why pacman was doing this but I couldn't find a good answer (perhaps I'm only a white belt in Google-fu).

There are quite a few projects on github where pacman has been added to LFS.
A google search gives me at least 7 projects.
For example this one: https://github.com/EastAPOLO/lfs-pacman
And even after you completed LFS you can try this: https://github.com/uditkarode/lfspacman

In my opinion most existing package managers are too tightly intergrated for the specific distro.
Slackware's pkgtools are so simple they can be used anywhere, next one in line is pkgutils from CRUX.

What is your goal exactly?

budrz89 03-26-2020 06:34 PM
I know that there are several projects out there with pacman on LFS, but some of them are either
automated and/or using systemd.

My goal is to build LFS manually with System V and having pacman as it's package manager. The
closest one to the idea that I had in mind is the project that I've mentioned but there are some
hiccups in the end, as stated in the link that you've provided: https://github.com/EastAPOLO/lfs-pacman

I'm trying to understand why those problems occur towards the end in finishing up LFS using pacman. It
seems that it shouldn't matter which package manager you use but you seem to be saying that each package
manager is somehow closely tied with it's distro. I don't understand how that is the case. I mean, it's
not like a package manager somehow "knows" distribution you're using, is it?

Could you explain why and how they are tightly integrated?

A few things make pacman not that ideal for LFS.
Pacman does not allow root to build packages without tricks. Pacman assumes a filesystem hierarchy as used by arch linux which differs from lfs.

And if you are going to use pacman and the existing repos from archlinux, you will end up with arch linux.

OK, that makes sense.

Seems like Artix Linux is what I'm thinking of or would end up building anyway, even if I could get past those problems. Never used it before but I guess it could be another project.

As for building LFS, I should look into pkgutils from CRUX. I'm curious to see how to integrate that into LFS.

Thanks for your suggestions/info!

That was while they're were in chapter 6 and building packages under that user. Presumably once they booted into their LFS system it wasn't an issue. You can't run makepkg as root which is why the user was created in the first place. I've used pacman with my LFS install a bunch of times without the issue that person encountered.

@basica Ok, I will keep that in mind and try it again.

budrz89 04-12-2020 11:05 PM
I just finished chapter 6 and I checked the ownership of all of the files. I wrote a script (which I think works) that checks this:

Code:
#!/bin/bash -e

cwd=$(pwd)
rm -f $cwd/file-list

pushd /

filelist=$(find ./ -user bob -group users -type f -name "*" ! -path "./home*" ! -path "./dev*" ! -path "./sys*" ! -path "./sources*" ! -path "./run" ! -path "./tmp*" ! -path "./svn*")

for f in ${filelist[@]}; do
        ls -lah $f >> $cwd/file-list
done

popd
Most notably are some of the files that seem to not have the correct permissions (like in /usr/bin):

Code:

I'm at a loss. Is there any hope in fixing this? You think that if I place the correct permissions and ownerships that the problem would go away once I boot into it?

Alternatively, I was thinking of installing with pacman and then installing the "crude" way (e.g. ./configure && make && make install), but this seems cumbersome.

I wonder if instead the way the instructions on github (or linuxfromscratch hints) in creating the user ben (I called it bob), if just creating a regular user using useradd would solve this issue. In other words, I wonder if it's because it's in the way this user is being created, unless I'm not understanding something.
