It creates symbolic links in the dynamic root (/afs) that link an alias for a cell (usually a short name) to the full name for the cell. .PP The most common use of this configuration file is to allow short names for frequently used cell names. Traditionally, such short names would be created by the local \s-1AFS\s0 administrator by creating symbolic links in the \&\f(CW\*(C`root.afs\*(C'\fR volume. Such symlinks do not appear when Dynamic Root is enabled because, with Dynamic Root, the Cache Manager does not mount or look at the \f(CW\*(C`root.afs\*(C'\fR volume. \fICellAlias\fR is a replacement that allows such short names to be created under the client control. .PP If you configure a short name mapping such as \f(CW\*(C`ir\*(C'\fR for \&\f(CW\*(C`ir.example.org\*(C'\fR, the mapping of \f(CW\*(C`.ir\*(C'\fR to \f(CW\*(C`.ir.example.org\*(C'\fR for the read/write version of the \f(CW\*(C`root.cell\*(C'\fR volume for that cell will be created automatically. There is no need to list that alias separately. \fBafsd\fR will report an error on startup if the dotted entry is listed separately. .PP The contents of the \fICellAlias\fR file should consist of one line of two whitespace-separated columns per alias. The first column is the real name of the cell, and the second column is the alias that should be created. .SH "EXAMPLES" .IX Header "EXAMPLES" The following \fICellAlias\fR file: .PP .Vb 2 \& prod.example.com prod \& test.example.org testcell .Ve .PP results in the following symbolic links: .PP .Vb 4 \& /afs/.prod \-> /afs/.prod.example.com \& /afs/prod \-> /afs/prod.example.com \& /afs/.testcell \-> /afs/.testcell.example.org \& /afs/testcell \-> /afs/testcell.example.org .Ve .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBfs_newalias\fR\|(1), \&\fBfs_listaliases\fR\|(1), \&\fBafsd\fR\|(8) .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2007 Jason Edgecombe .PP This documentation is covered by the \s-1BSD\s0 License as written in the doc/LICENSE file.
