PKGNG upgrade / reinstall overides directory permissions

[Arnaud Houdelette]

Hello.

I'm currently testing pkgng and poudriere as a replacement for old pkg 
and pkg_jail.

When upgrading/reinstalling a port, pkg install / pkg upgrade resets the 
permissions of the directories created by the ports which already exist.

Old pkg_add did not have this behavior.

For example,
- install lighttpd
- chmod 750 /var/log/lighttpd
- pkg install -f lighttpd

=> /var/log/lighttpd mode is reset to 700.

Is this behavior correct ? Is there some option to avoid this ?
