using_file_mounts.yaml

# Example: using file mounts
#
# File mounts sync local files (or cloud URLs) to the VM where a Task will run.
# Syncing is done before the Task's execution so that it can access these files.
# After syncing, the paths can be opened, read, or written as usual.
#
# Caveat:
#
#    Destination paths may be created as *symlinks* under the hood.  Some
#    commands may require flags to follow symlinks (e.g., ls -H; du -L).
