Subject: Restrict package locales to en_US
X-Git-Tag: lxc-2.1.0~197^2~2
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=91a5f346123eec598f43932b71b80cc48a60e6da;p=thirdparty%2Flxc.git

Restrict package locales to en_US

Adjust locale setup to official Fedora cloud setup. This will
shrink the image size for e.g. Fedora 25 from around 350MB to
260MB.
