 Single user mode is a minimal environment with minimal functionality. It can be useful for investigating boot issues or network issues as fewer services may run in the background, and, depending on the runlevel, a filesystem may not even be automatically mounted. This is useful to investigate situations such as a corrupt filesystem, a broken fstab, or network connectivity (incorrect iptables configuration).
 
 Some distros will automatically drop you into single user mode or emergency mode if the VM is unable to boot. Others, however, require additional setup before they can drop you into single-user or emergency mode automatically.

 ## System Request (SysRq)
 A SysRq is a sequence of keys understood by the Linux operation system kernel, which can trigger a set of pre-defined actions. These commands are often used when virtual machine troubleshooting or recovery can't be performed through traditional administration (for example, if the VM is hung). Using the SysRq feature of Azure Serial Console will mimic pressing of the SysRq key and characters entered on a physical keyboard.
