Generally:
Disks with Luks have to be opened first before being able to be mounted. After opening, a virtual blockdev is created, with the UUID you put into fstab. As the Luks disk is not unlocked at boot, the virtual blockdev doesn't exist yet, so systemd hangs for 3 mins or so trying to find/wait for it to mount it
Usually, it should continue to boot after timeout. If it does not, you need a USB Stick with Linux, boot that, mount the root partition and edit the fstab
It's only used as a minor tool in real-life, non-faked projects. A tool that's very expensive and rarely of objective usage. As soon as the bubble pops, the market will essentially wipe it out.
According to EICAR's specification the antivirus detects the test file only if it starts with the 68-byte test string and is not more than 128 bytes long.
Fuck me, I sometimes just do a find / -name "*.pacnew" and diff manually
