I've used libeatmydata to quickly perform apt-get update. Now I want to run standard fsync to make sure that everything is written to disk. How can I do it? Preferably a small script / binary, and for bonus points fsync for real even when libeatmydata is pre-loaded

Calling sync should do the trick.

You can also press Alt+SysRq+S.

Where would that magic key be on my MacBook "smalish" keyboard? – Dima Dec 6 '10 at 0:35
    
Sorry, I've no idea. But this would be a great question to ask here, if only for future reference. – Stefano Palazzo Dec 6 '10 at 2:24
