Beautiful response, just what one expects from a dedicated professional.

Diff has a dependency on mtab?

Of course mount does, but IT IS DOCUMENTED.

I didn't ask for the dependency to be removed, but rather TO BE DOCUMENTED.

The dependency on /etc/mtab is very usual. Many shell programs, such as diff and mount, depend on /etc/mtab on many operating systems. This is a common sense, so not worth mentioning particularly.

If you are doing an unusual thing, you must know how the system works. That's it.

It seems that grub uses, or looks at /etc/mtab when it installs or sets itself up for the first time.

This is not documented anywhere, so if one is doing something really ugly and bizarre (like backing a system up to a different disk, removing the boot disk, forgetting the proper partition layout (which was overly complicated) and completely forgetting about /etc/mtab (which documented said partition layout) then one could (hypothetically of course) spend several days trying to figure out why he can't get the machine to boot, even though grub is finding the kernel and the initrd, but things keep blowing up after pivotroot.

Dunno exactly where in the docs to make the change, but if you'd like me too, I can give it a whack and submit the changes.

I don't know if version 2 does the same sort of ugliness, but having had to do wierd emergency disk drive broke fix it now now now things in the past, the more of the process that is configurable at the command line, and the more that is documented in the man page (use of info considered harmful), the better life is.

Thanks.
