+Subject: [PATCH] isula-build: change default umask of isula-builder process
+
+As the daemon process, the working umask 0027 is not suitable.
+0022 is better.
+
+Take this example:
+isula-builder using 0027, the working dir of container for RUN command
+(overlay/merged dir, as an example), has the 0640. Then developer changes
+working user in RUN command to a non-root user, it will not have
+correct permission to work.
