Boot Hangs After Editing fstab

I was trying to set up my BBB to automount a USB drive, so I edited the /etc/fstab file, adding this line:

/dev/sda1 /media/disk1 vfat auto,umask=0 0 0

I forgot to create the mount directory, so when I try reboot the BBB, the thing just hangs. I can’t get a console nor can I ssh into it. Did I just brick the thing? How do I recover from this problem?

Add "single" to your bootargs/cmdline/etc.. to boot into single user
mode and create the directory
