Subject: nspawn: Fix incorrect usage of putenv
X-Git-Tag: v247-rc1~470
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=6f646e01755df587bb33dae4ca78cdaad5721f5e;p=thirdparty%2Fsystemd.git

nspawn: Fix incorrect usage of putenv

strv_env_get only returns the environment variable value. putenv expects
KEY=VALUE format strings. Use setenv instead to fix the use.
