Actually, creating the 'data' directory first doesn't work either:

[delirium:postgres] ~
(17) mkdir data
[delirium:postgres] ~
(18) initdb -D /software/postgresql-8.0.0/data
The files belonging to this database system will be owned by user "postgres".
This user must also own the server process.

The database cluster will be initialized with locale C.

fixing permissions on existing directory /software/postgresql-8.0.0/data ... ok
creating directory /software/postgresql-8.0.0/data/global ... initdb: could not create directory "/software/postgresql-8.0.0": Operation not applicable
initdb: removing contents of data directory "/software/postgresql-8.0.0/data"


Since there's subdirectories that need to be created, it still runs into
the problem.  I don't know why the command 'mkdir' doesn't exhibit the
same problem as the function 'mkdir', but running:

   mkdir /software/postgresql-8.0.0

produces the correct error "File exists" on my system.  I suspect the
'mkdir' command probably checks to see if the directory exists first
before trying to create it, which avoids the problem.
