I burned a Kali Linux ISO file to an SD card so that it would be faster than an optical disc. When I booted, systemd got stuck on what looked like a couple processes waiting for each other to finish (one of them had something to do with Tor, the other just said "bootstrap"). Because it had no time limit, the wait persisted indefinitely. If I could simply reconfigure it to time out after a minute or so, the problem would be fixed. Also, I've had no difficulty booting the same ISO file in VirtualBox; this only happens when I try to load it on the bare metal. I'm using an older version of Kali, from November 2018, so maybe this is a bug that has been fixed since then, or it could be something that I'm doing wrong. Any advice?
