pure-ftpd, setting _flags in rc.conf

[Joel CARNAT <joel%carnat.net@localhost>]

Hi,

I'm trying to pass flags to pure_ftpd but I don't seem to use the right 
syntax (or the package don't support it).
I'm using (in /etc/rc.conf"):
   pure_ftpd=YES
   pure_ftpd_flags="-4 -A -e"
But pure-ftpd is still started with no flags.
Debugging the start script process, I think I use the right command:
   + eval 'rc_flags=$pure_ftpd_flags'
   ++ rc_flags='-4 -A -e'
What's wrong with my conf ?

TIA,
   Jo
