+Before installing an upgraded version of Netatalk that is linked against a newer BerkeleyDB lib, run `dbd \-u \&.\&.\&.` from the OLD Netatalk pior to upgrading on all volumes\&.

.SH "WARNING"
.PP
-If you want/need to run an \-r \-f rebuild after adding \'cachecnid\' to a volume configuration, you must run a rebuild with \-r alone at first in order to sync all existing CNIDs from the db to the AppleDouble files!
+In order to be able to run
+\fB\-rf\fR
+reconstructing the CNIDs in the database from the
+\fIAppleDouble\fR
+files, make sure you\'ve run a
+\fB\-r\fR
+rebuild sometimes before, where the CNIDs then would have been synched between database and
+\fIAppleDouble\fR
+files\&.
+.PP
+Also be careful about the option
+\fBnocnidcache\fR\&. Avoid this option if at all possible, because if prevents you from being able to use
+\fB\-f\fR\&.
.SH "CNID BACKGROUND"
.PP
-The CNID backends maintains name to ID mappings\&. If you change a filename outside afpd(8) (shell, samba), the CNID db will not know and doesn\'t reflect that change\&. Netatalk tries to recover from such inconsistencies as gracefully as possible\&. The mechanisms to resolve such inconsistencies may fail sometimes, though, as this is not an easy task to accomplish\&. E\&.g\&. if several names in the path to the file or directory have changed, things may go wrong\&.

.PP
If you change a lot of filenames at once, chances are higher that the afpds fallback mechanisms fail, i\&.e\&. files will be assigned new IDs, even though the file hasn\'t changed\&.
