+  * User No Dump
+  * User Immutable
+  * User Append
+  * User Opaque
+  * System Archived
+  * System Immutable
+
+== Implementation status ==
+
+Implemented since repository revision 92 (2007-01-29).
+
+== Notes ==
+
+  * Note that some flags have overlap and may be duplicated with other metadata support. Most notably this happens with [metadata_linux_attrib Linux EXT2 file attributes].
+  * Archival of flags is implemented using the `st_flags` struct member of the [metadata_stat stat metadata] on platforms that support it.
+  * Extraction of flags is implemented using the chflags(2) APIs on platforms that support it.
