What is an unsafe operation? Anything that's dumb and might lose data?
For example
The possibilities are sheer endless.
And?
- What is the *right* way to update a file?
fd = open(tmpfile, ...);
write(fd, ...); // or any other update
fdatasync(fd);
rename(tmpfile, realfile);

That's not real and it's not complete. tmpfile is undefined, errors
aren't handled and you have lots of unlisted assumptions or regressions.
