Well, depends on how you define "open files are overwritten". On
Linux, it is like you say. But on Windows and HP-UX, you CANNOT
replace a file, if it's still opened somewhere. Eg. you cannot
replace /bin/sh. Instead, a new file will be created and after
a reboot, the new file will be moved in place (that's how it
works on HP-UX, on Windows you cannot overwrite opened files.).
What I mean: On Linux, you can replace /bin/sh even if it used.
You cannot overwrite the used inodes/blocks, that's absolutely
correct, but that's not what I meant.
