April fool joke on supergrub2 usb boot disc.
by andrewysk from LinuxQuestions.org on (#5G4JK)
I have got a grub that failed to detect existing win7 installation on my wife pc after i installed endea xfce on her pc (now is dual boot). Hence when she need win7, i temporary gave her this supergrub2 boot usb to detect and go into win7 partition. **no mood to learn to go into grub to modify it**
On 1st of April, this april fool joke keep popping up and wasting her time. Initially she was scared to death.. later on we saw it was just an april joke.

But each time she use the supergrub2 usb stick to start up pc, it display the same april fool joke. (i was expecting it to be only ONE TIME JOKE, but it kepts doing that for the whole day).
My wife shut down pc for 4 times that days.. hence she have to wait for the april fool joke to end before she can start her windowos partition, what a waste of time...
This made me thinking, we are lucky , this programmer means no harm.. but who know one day we might used a open source software that has embeded trojan horse that might activate in a certain future, just like this supergrub2.
This supergrub2 ; i have burnt it in usb disc many months before.. and it embeded joke only activated now , at april fool day.

The developer "adrian15" said, the simple code is as shown in this github. We can modify it ourselves..
https://github.com/supergrub/supergr...ub.cfg#L24-L28
I am thinking of edit the grub.cfg (where the april fool code resided) direct of the usb bootdisc.
When i plugged in the live usb, lsblk shows it /dev/sdd and /dev/sdd1
Code:$ mkdir /mnt/supergrub2_bootdisk/
$ sudo mount /dev/sdd1 /mnt/supergrub2_bootdisk/
mount: /mnt/supergrub2_bootdisk: wrong fs type, bad option, bad superblock on /dev/sdd1, missing codepage or helper program, or other error.Anyway to access/ read into liveusb disk ?
