View Full Version : bootup and shutdown message meanings

1st January 2016, 01:45 AM
Have installed f23 onto a flash drive rather than the hd (working fine so far) as I did with 22. I notice that on bootup and shutdown 2, 1 line messages occur: The first one complains that something is invalid and uses the initials BGRT. The second line contains prot (my note did not spell this out) loading x.509. They do not remain displayed long enough to get a complete description.
I will be appreciative if someone can explain the meanings, thanks.

I see your first one on every boot up. It's harmless, and this link (http://ubuntuforums.org/showthread.php?t=2264380) should explain it.

The x.509 has to do with certificates. I find this in my dmesg:

$ dmesg | grep -i "x\.509"
[ 0.679271] Loading compiled-in X.509 certificates
[ 0.680249] Loaded X.509 cert 'Fedora kernel signing key: 89ceaf5380b1d1504056cb00aa3c46346beb2e05'
And yes, it's compiled into the kernel:

$ grep -i certificate config-4.2.8-300.fc23.x86_64

Edit: I see the link I gave is also a link in the forum thread nsnbm linked to.
