Patch summary: * check for 'nousb' argument on kernel command line in /etc/grub.conf within the bootloader_nousb_argument check in a case-insensitive way * update comments where appropriate * add test attestation timestamp * replace path + filename ind construct with filepath one Testing report: * Tested on RHEL-6. Works fine.
Note that ALL kernel parameters listed below are CASE SENSITIVE, and that a trailing = on the name of any parameter states that that parameter will be entered as an environment variable, whereas its absence indicates that it will appear as a kernel argument readable via /proc/cmdline by programs running once the system is up.
