Hello world,

I have an overlay and recently I changed all permissions in my home folder to 700
everything works fine, except ebuild merge, I keep my ebuild locally and on github
and everytime now I have to push, sync and rebuild with portage instead of locally
testing an ebuild

I just noticed this today

What permissions should I give it?

Code:

ari@ari-gentoo (main) yafetch % sudo ebuild yafetch-1.14.ebuild merge
(enter password for ari)
Appending /home/ari/Ari/coding/resources_/overlay/dinolay to PORTDIR_OVERLAY...
!!! Permission Denied: /home/ari/Ari/coding/resources_/overlay/dinolay/profiles/thirdpartymirrors


but /home/ari/Ari/coding/resources_/overlay/dinolay/profiles only includes repo_name file...
This is weird

If you need more information don't be afraid to ask and all files and stuff can be found here:
https://ari-web.xyz/overlay

Thanks in advance

The overlay needs to be readable by "portage" user.

Because your home directory is 700, emerge will not be able to enter it because the emerge process drops down to the portage user for several tasks.

It is not advised to put an overlay in a /home for this reason.

Oh, I'll just put it in /usr/local/src or something then, thanks

nvm didn't work either, I will figure something out

If you still need help, please post the full error message, and the permissions of all the intervening layers. As is, we cannot reproduce the failed environment, so our ability to help is limited.

I did, it's in the post, like it's literally all it says, nothing else, I wish I could give more information that that
unless I can :shrug:

Anyway here is a screenshot: https://files.ari-web.xyz/files/yafetch_gentoo_build_dinolay.jpg

and everything under that is all permissions of 700

If you had put it in /usr/local/src, and provided the full error output from having put it there, then somewhere in the thread would be a copy of an error message involving that path. Currently, I see nowhere in the thread where you have posted the full error message, and the permissions of all the intervening layers, all taken from a single attempt, and all in a way that we could actually attempt reproduce your problem. The closest you came is this:

Except that vaguely describes the permissions, instead of showing them. Note however that 700 is probably wrong for this use, unless everything that is mode 700 is also owned by the portage user. mv already told you how to fix this:

If you had run that command, you would not have permissions of 700 all the way down. a+rX by definition would have made it at least 755, if not more open.

Okay, the error message was the same everywhere including /usr/local/src, but about the 755 thing,
I don't want to make my home dir 755, is there a way I could not do that and put it somewhere else instead?

What does this command show:
Code:
namei --long /usr/local/src/profiles/thirdpartymirrors


In addition,
Quote:
Appending /home/ari/Ari/coding/resources_/overlay/dinolay to PORTDIR_OVERLAY...

says that this repository is not set up properly and known to portage. This should be corrected.

Also, why are you running:
Code:
sudo ebuild yafetch-1.14.ebuild merge


This is not the correct way to install anything.

Always use emerge to install, preferably by a full login to root.

As I mentioned in the post profiles/thirdpartymirrors does not exist, only repo_name :)

I have no idea why it's showing that, I am just testing my overlay packages before releasing

I am not trying to install, it's just a sideeffect, I just want to test if the ebuild works

Greeting Ari_ancher, We met again in gentoo forums talk about repo/ebuild setup :-)

I can't help myself feeling somehow I am responsible for your today's question. I am not sure if you recall my previously advise post about [solved] ebuild failing to handle redirects which create a debate with Hu about should a directory permission be setup to world wide open. I am glad you took the position to protect your home directory, you apparently understand the security implication.

I am confuse your statement

what do you mean only repo_name? Usually repo_name is a portage artifact, it is a file located in a overlay's profiles directory with content name the repo. Since your said profiles/thirdpartymirrors does not exist could you let us know what do you mean repo_name? do you mean it is a file but just in somewhere else but not /usr/local/src/profiles/thirdpartymirrors/?

PORTDIR_OVERLAY is a deprecated portage artifact, it is a variable usually define in make.conf it usually contain a list of directories, and each directory is where a overlay directory structure, one of the sub-directory is *profiles/* which have a file name repo_name. Today you should use /etc/portage/repos.conf for the same effect.

If you just want to test your ebuild logic, you can use ebuild yafetch-1.14.ebuild compile. You don't need sudo.
In general emerge/portage is a complete system where it take a program from source code to process into package format and install into current running system with match security/configuration setting for the current system. If you desire is to matching your design for your running system. then the permission error is a indication your design ebuild system does not match your running system configuration.

oh wow, thanks :)

Solved!

ebuild compile works :)
