I installed the package of postfix and it installed is self into 
/usr/bin with out any help from me.

This is now I know that. I swapped a empty drive with my live system 
drive. Installed the sysinstall kern developer option to get full 
binaries and sources. After the install I set chflags schg /dir/ and 
/dir/* for these dir. /bin /boot /lib /libexec /sbin /usr/bin 
/usr/include /usr/lib /usr/libexec /usr/sbin. This should have protected 
all those RELEASE base directors and all the files in then. With the dir 
also having schg on, no files should have been able to be added to it. I 
then did a ls -lo /dir > file to save copy of their content. Then I did 
pkg_add -r postfix-current. After which i did another ls -lo /dir > file 
and to my surprise i see all these new files have been added to /usr/bin.

What am I to think? How else would you explain this?
