I have recently added some useful extra functionality to the Hurd's sync program, but in its canonical use with no arguments it is just the same as the usual Unix version that calls the `sync' function. Since I just added these options days ago, there is nothing that depends on them. I think it is fine for sync to be the old one from fileutils. I will rename the Hurd program to `syncfs' or something like that (the new argument parsing I added lets you sync particular filesystems rather than everything, and control the flags in the Hurd RPC).
Sounds great, but ... ... last time I accidently replaced my Hurd sync with the one from fileutils it didn't work adn my system hung on it. I haven't investigated it because the standard Hurd sync works fine, but you might want to check this before renaming it. Mark
