docs/manual: do not suggest to create a symlink for shared download directory
Creating a symbolic link for the download directory is really not a useful suggestion, since we have the much better solution of the BUILDROOT_DL_DIR environment variable. So emphasize this solution instead, and remove the suggestion of the symbolic link.

The various tarballs that are downloaded by Buildroot are all stored in

+DL_DIR+, which by default is the +dl+ directory. If you want

The various tarballs that are downloaded by Buildroot are all stored

in +BR2_DL_DIR+, which by default is the +dl+ directory. If you want
|

to keep a complete version of Buildroot which is known to be working
|

with the associated tarballs, you can make a copy of this directory.
|
||||
This will allow you to regenerate the toolchain and the target filesystem
|

with exactly the same versions.

If you maintain several Buildroot trees, it might be better to have a
|
||||
shared download location. This can be accessed by creating a symbolic
|
||||
link from the +dl+ directory to the shared download location:
|
||||
|
||||
-----------------
|
||||
$ ln -s <shared download location> dl
|
||||
-----------------
|
||||
|
||||
Another way of accessing a shared download location is to create the
|
||||
+BUILDROOT_DL_DIR+ environment variable. If this is set, then the
|
||||
value of DL_DIR in the project is overridden. The following line
|
||||
should be added to +<~/.bashrc>+.
|
||||
shared download location. This can be achieved by pointing the
|
||||
+BUILDROOT_DL_DIR+ environment variable to a directory. If this is
|
||||
set, then the value of +BR2_DL_DIR+ in the Buildroot configuration is
|
||||
overridden. The following line should be added to +<~/.bashrc>+.
|
||||
|
||||
-----------------
|
||||
$ export BUILDROOT_DL_DIR <shared download location>
