A follow up to this - directory server can import from stdin and export 
to stdout, so you can do this:
db2ldif -n userRoot -a - | gzip > db.ldif.gz
and
gunzip -c db.ldif.gz | ldif2db -n userRoot -i -

For initialization usage, I guess that would mean online init (or remote 
bulk load using ldapmodify -B).  In that case, since the data is BER 
encoded already, it would be better to investigate attribute value 
compression, as discussed elsewhere in this thread.
