SHOW VARIABLES LIKE '%dir%'; (basedir and datadir)

[Nils Valentin]

Hello MySQL Fans,

This time I am using 4.0.13-max (tar format from www.mysql.com) on
Redhat 9.

I have an understanding question why would the command SHOW VRAIABLES
give me once the real output and once the symlink ouput for directory
names ?

Sample (datadir and basedir) :

mysql> SHOW VARIABLES LIKE '%dir%';
+----------------------------+--------------------------------------------+
| Variable_name | Value |
+----------------------------+--------------------------------------------+
| basedir | /usr/local/mysql-max-4.0.13-pc-linux-i686/ |
| bdb_logdir | |
| bdb_tmpdir | /tmp/ |
| datadir | /usr/local/mysql/data/ |
| innodb_data_home_dir | |
| innodb_log_arch_dir | ./ |
| innodb_log_group_home_dir | ./ |
| innodb_max_dirty_pages_pct | 90 |
| tmpdir | /tmp/ |
+----------------------------+--------------------------------------------+
