+Description: Fix garbd's -w / WORK_DIR parameter
+Forwarded: https://github.com/codership/galera/issues/672
+Last-Update: 2025-01-26
+
+    The -w parameter (typically enabled from /etc/default/garb with the
+    WORK_DIR= variable) allows to save the gvwstate.dat file with cluster
+    information elsewhere than non-writable / .
+
+    It appears a mandatory semicolon to separate the internal parameters
+    configuration string was somehow lost in garb/garb_config.cpp during two
+    possibly conflicting commits in upstream's repository:
+
+      Add command line option to specify desired working directory where
+
+    https://github.com/codership/galera/commit/29d906e6239e0a4111214a8bf7f0779308f479f8
+
+    and:
+
+    Fix renaming of fc_master_slave to fc_single_primary. In particular don't

+      https://github.com/codership/galera/commit/b3c498328b699c733e5c881fcc66a6f721ac674d
+
+    causing a syntax error when the resulting internal parameter base_dir gets
+    used:
+
+    FATAL: Exception in creating receive loop: More than one value for key 'gcs.fc_single_primary' at ' gcs.fc_single_primary=yes base_dir=/tmp' in parameter list.
+
+    Restore the mandatory missing semicolon to fix this issue.
