What happened to NO_OPENSSH in make.conf with FreeBSD 7?

[FreeBSD]

Hello everyone,

With FreeBSD 6.2-Release, I added the option NO_OPENSSH=true in the 
make.conf I use to build jails. But, I just rebuilded a jail in FreeBSD 
7-Release and I realized at the mergemaster step of the update that 
there were a lot of files related to OpenSSH that needed to be 
installed. By checking the man and /usr/share/examples/etc/make.conf, I 
find no reference to this option anymore.

Can someone shed some light on this?

Thank you very much,

Martin
