PostPosted: Fri Jun 22, 2018 12:21 am    Post subject: Issues with patches (Gentoo Live minimal & SysRescueCd) Reply with quote

Can somebody please tell me any reasons why wouldn't user patches be applied in a live environment with a Gentoo Minimal or SysRescueCd iso? I've done everything according to this article https://wiki.gentoo.org/wiki//etc/portage/patches , but whatever I do is 'ignored' somehow during compilation. I know I'm doing something wrong, but I don't understand what it is. :?
I'd also like to add that user patches are applied if I'm doing everything from an installed system like the one I'm using atm or on a usb flash drive. :o

There are many reasons, but they are all variants of "You did something wrong." Without knowing what you executed, we cannot tell what you may have done wrong. Please post the output of find /etc/portage/ -ls and the build log of an affected package. You can truncate the log at the start of upstream's configure/make process. We only need to see the Gentoo preparatory stages.

Here you go. I assume this is enough information? :)

From the look of it, it should work. The ebuild calls "kernel-2_src_prepare()", which itself calls "eapply_user", and your patches are in the right location.

You could try to rename "/etc/portage/patches/sys-kernel/ck-sources-4.16.16" to "/etc/portage/patches/sys-kernel/ck-sources", but that is a shot in the dark...

And running as root? (I notice the patches are readable by root only)

@Yamakuzure
nope, doesn't work anyway.

@freke
yeah, running as root.


Guess, I'll just make a custom install on my flash drive, because for some reason that's the only way it works. Hmmmmm... :x

Are you sure? Normally, Portage will change to an unprivileged user for most of its work. If you did not disable that, then, no, you are not running as root (nor should you be). Did you try fixing the permissions? The patches need to be readable by the user that Portage uses, and it's generally safe to make them world readable.

On the bright side, the Wiki page you cite completely fails to mention that you need to do this. So while it was incorrect for you to make the files root-only, you did not deviate from the instructions.

Okay, it would be good to know what this is all about either way.

If you solve it, please post back with the explanation. I expect it will be as I described above: a permissions problem.

Yeah, I should make sure. I'm going to do it in a short while. I thought about it, and most likely this is really what is causing my 'problem'. I'll check again and get back to you guys. :)

Okay, now I checked and it was a simple file permissions issue for the /etc/portage/bashrc file. I changed it and now it patches are being applied just fine.

Thanks for the help, guys!
