+Subject: [PATCH 1/3] pseudo_client.c: protect pwd_lck against magic
+
+While attempting to diagnose unexpected uid/gid assignment I added
+--without-passwd-fallback to the pseudo build.  This caused build
+failures due to inability to lock /etc/passwd.
+
+Instrumentation revealed that attempts to create the lock file ended up
+with pseudo_etc_file() creating the correct lock name, but the
+subsequent open had an extra PSEUDO_PASSWD directory prefix causing
+it to fail.
+
+Inspection of pseudo_client shows the only other use of PSEUDO_ETC_FILE
+to be protected against magic.  Applying the same shield to the
+unprotected calls in pseudo_pwd_lck_{open,close} fixes the issue.
