Homebrew Regarding about IOS

[jazvdb]

If you install a new IOS will it replace the old IOS?
or....?

 

[OSW]

yes, it will overwrite any old IOS of the same number (or title ID).

For example, if you have IOS30 installed,

You install an updated version of IOS30, it will overwrite.

You install IOS60, then IOS30 will be untouched.
