Linux has -t auto; haven't looked at how it works.


It's implemented in mount(8). It has a table of magic numbers and offsets
and tries all of them in a well defined order. If everything fails it
tries a few heuristics whether the filesystems might be a FAT filesystem
as thos don't have magic numbers.


So in your opinion and experience, what are the pros and cons of maintaining a table of magic numbers?
