>Organization:
Southern Ural State University
>Environment:
-stable
>Description:
1. Fix for /etc/rc.diskless2 - utilities from /usr were used before mount -a
was called.
2. /etc/rc.diskless1: added configuration option "diskless_sync_pw" to take
password files from server's /etc, not from /conf/*/etc.
>How-To-Repeat:
Try to boot diskless FreeBSD machine using FreeBSD NFS server
