Bug 713326 – app-portage/gentoolkit: euse can't enable use flags when make.conf is a include directory

• Product: Gentoo Linux
• Status: UNCONFIRMED ---

[Description Citizen Kepler 2020-03-18 22:09:18 UTC]

When /etc/make.conf is a directory containing include files, the euse tool can not enable use flags.

Version: 0.4.6


Reproducible: Always

Steps to Reproduce:

The issue occures when /etc/portage/make.conf is used as a include directory and not a file.  The euse tool does not expect this and fails poorly. 

Replication

Backup current make.conf 

$> mv /etc/portage/make.conf /etc/portage/make.conf.backup

Create make.conf include directory

$> mkdir /etc/portage/make.conf

Make a copy of the backed up make.conf in the new include directory.
 Note: I used local, but the filename can be anything, or multiple files

$> cp /etc/portage/make.conf /etc/portage/make.conf/local

With the Environment setup, I issue a euse command to enable a use flag (alsa in this case) 

$> euse -E alsa
/usr/bin/euse: line 278: source: /etc/portage/make.conf: is a directory
Adding flag "alsa" to make.conf
cp: -r not specified; omitting directory '/etc/portage/make.conf'
/usr/bin/euse: line 1162: /etc/portage/make.conf.euse_backup: No such file or directory
/usr/bin/euse: line 1267: /etc/portage/make.conf: Is a directory
/etc/portage/make.conf was modified, a backup copy has been placed at /etc/portage/make.conf.euse_backup
$> 


Expected Results:  
I expect the script to fail gracefully citing that a make.conf include directory is not supported, or make changes to support a make.conf include directory.

Relevant other make.conf include directory bug I found with euse:

#556514 - app-portage/gentoolkit: euse can't source files from make.conf directory

This is a similar bug, but relating to sourcing in the files from the include directory.  The case filed above is reporting changes to the make.conf file/directory that are in error.
