I ran into an issue where if conf --olddefconfig is used to update a config which is not on the same mounted volume, the conf_write fails. The final rename of tmpconfig fails to move the file across volumes. For example, this fails (on my host /tmp is tmpfs): $ touch /tmp/test.config $ export KCONFIG_CONFIG=/tmp/test.config $ ./scripts/kconfig/conf --olddefconfig Kconfig This is only an issue when no name is passed to conf_write. When a name is passed, there is code to determine the directory and write tmpconfig there. The following patch uses the same dirname code for the environment variable, when no name is passed to conf_write. Let me know what you think.
