Just run the following code:
That said, I really couldn't care less if we eventually just nuked the entire major/minor number distinction and let applications just print the dev_t directly. This means `ls -l' would just print a single number. POSIX doesn't standardize major/minor numbers anyway. Just the dev_t. Unfortunately I do realize this probably breaks a lot of high profile software. -- Ed Schouten <[email protected]> WWW: http://80386.nl/
