Boot process

Edit online

New boot scripts added to the /etc/inittab file on Trusted AIX® systems. The new boot scripts are rc.mls.boot, rc.mls.net, and rc.mls, and are executed in that order.

The steps executed in the rc.mls.boot script are:
  1. An interactive integrity check is run to prompt the user for information on how to handle each discrepancy (using the trustchk command)
  2. Set the configuration mode kernel security flags (using the setsecconf command)
  3. Set the system labels (Minimum and Maximum Sensitivity Labels and Integrity Labels)
  4. The configuration mode kernel security flags are displayed on the screen
The steps executed in the rc.mls.net script are:
  1. Initialize the Trusted AIX sub-system.
  2. If the /etc/security/rules.int file exists, it will load the rules database into the kernel.
The steps executed in the rc.mls script are:
  1. Initialize the Trusted AIX sub-system.
  2. If the /etc/security/rules.int file exists, it will load the rules database into the kernel.
Note: Any change to the boot scripts can result in a system malfunction.
