Valid values for -+.I junction-type -+are -+.B nfs-basic -+or -+.BR nfs-fedfs . -+.IP -+For the -+.B add -+subcommand, the default value if this option is not specified is -+.BR nfs-basic . -+For the -+.B remove -+and -+.B lookup -+subcommands, the -+.B \-\-type -+option is not required. The -+.BR nfsref (8) -+command operates on whatever junction contents are available. -+.SH EXAMPLES -+Suppose you have two file servers, -+.I top.example.net -+and -+.IR home.example.net . -+You want all your clients to mount -+.I top.example.net:/ -+and then see the files under -+.I home.example.net:/ -+automatically in -+.IR top:/home . -+.P -+On -+.IR top.example.net , -+you might issue this command as root: -+.RS -+.sp -+# mkdir /home -+.br -+# nfsref --type=nfs-basic add /home home.example.net / -+.br -+Created junction /home. -+.sp -+.RE -+.SH FILES -+.TP -+.I /etc/exports -+NFS server export table -+.SH "SEE ALSO" -+.BR exports (5) -+.sp -+RFC 5661 for a description of NFS version 4 referrals -+.SH "AUTHOR" -+Chuck Lever -diff --git a/utils/nfsref/remove.c b/utils/nfsref/remove.c -new file mode 100644 -index 0000000..1a4e371 ---- /dev/null -+++ b/utils/nfsref/remove.c -@@ -0,0 +1,145 @@ -+/** -+ * @file utils/nfsref/remove.c -+ * @brief Remove junction metadata from a local file system object -+ */ -+ -+/* -+ * Copyright 2011, 2018 Oracle.
