+The redirection accomplishes logging to file:$WORKDIR/logs/kvm.log-2 outside the kvm instance.
+===== .config lifecycle (as of kernel-autobuild 0.7-devel6) =====
+  * ''kernel-autobuild --config some-dotconfig-file --dotconfig-setting DEF=val --dotconfig-setting-file file''
+  * ''kab_identify_kernel_config_file''
+    * looks for the latest (time) kernel build tree, sets ''$LASTVERSION''
+    * if ''$LASTCONFIG'' isn't set (this would be by ''--config'' )
+      * checks for the latest ''source/config-${LASTVERSION}*'', sets ''$<nowiki>__</nowiki>LAST_VERSIONED_CONFIG''
+      * if ''$<nowiki>__</nowiki>LAST_VERSIONED_CONFIG'' is a file and exists set ''$LASTVERSION'' to ''$<nowiki>__</nowiki>LAST_VERSIONED_CONFIG''
+      * elsif ''source/config'' is a file and exists set ''$LASTVERSION'' to ''source/config''
+      * elsif ''/boot/config-$(uname -r)'' is a file and exists set ''$LASTVERSION'' to ''/boot/config-$(uname -r)''
+      * else error && abort
+  * ''kernel-autobuild'' reports ''$LASTCONFIG'' to ''$INFO_DIR/LASTCONFIG''
+  * ''kab_downloads'' copies ''$LASTCONFIG'' to ''$SRC_DIR/config''
+  * ''kab_apply_dotconfigsettings'' calls ''kab_modify_dotconfig'' which
+    * reads ''$SRC_DIR/config''
+    * applies changes from ''--dotconfig-setting-file'' (if present)
+    * applies changes from ''--dotconfig-setting'' (if present)
+    * moves ''$SRC_DIR/config'' to ''$SRC_DIR/config-orig-YYYYMMDD-HHMMDD''
+    * creates ''$SRC_DIR/config'' with applied changes
+    * creates ''$SRC_DIR/dotconfig.changelog'' listing applied changes suitable for ''debian/changelog''
+  * ''kab_compile_and_package''
+  * backups an existing ''$BUILD_DIR/linux-*/.config'' to ''$SRC_DIR/config-orig''
+  * copies ''$SRC_DIR/config'' to ''$BUILD_DIR/linux-*/.config''
+  * runs ''make oldconfig''
+  * backups ''$BUILD_DIR/linux-*/.config'' to ''$SRC_DIR/config-oldconfig''
+  * ( build kernel )
+  * backups ''$BUILD_DIR/linux-*/.config'' to ''$SRC_DIR/config-$KSRCVER--${PVER}-$GLOBAL_DATE''
