Security Notes
ZeptoOS is completely configurable. You may choose to allow user login access, or restrict it. However you configure ZeptoOS, it is important to note that the default configuration from IBM is for the I/O Nodes to NFS mount the /bgl file system with full root privileges. This means that anyone who has root access on the I/O nodes can modify everything on the NFS server. On our machine, we have modified the service node to export /bgl read-only, without observing any adverse effects on the I/O nodes.
Configuring the Build
Unlike ZeptoOS V1.5 on Bluegene/L where it was required to run a configure script, in ZeptoOS V2.0 for Bluegene/P we have an ncurses based make menuconfig option.
