[uml-user] FAQ: 2.6.9 - why "make linux ARCH=um" fails?

[BlaisorBlade <bla...@ya...>]

Q: Why does "make linux ARCH=um" fail?
R: Just use "make vmlinux ARCH=um", which creates the "vmlinux" binary, which 
is what you must use.

Or even simply do "make ARCH=um", which is the same as:
make vmlinux modules ARCH=um

* Q: Why did you do this change?
R: This is the result of a change which allows /proc/kallsyms to work, 
allowing UML to print stack traces on panic.

* Q: Why did not you added a notice about "make linux ARCH=um"?
R: I did that, only it was merged after 2.6.9.

* Q: What did you do?
R: within next version, each time you do "make linux ARCH=um", a hardlink is 
created from linux to vmlinux. I.e. they are two copies of the same file, 
sharing the content. If you do a "make vmlinux ARCH=um", instead of leaving a 
stale linux file with the old content, or relinking it, we simply remove the 
vmlinux file. It is assumed that if you do "make vmlinux ARCH=um", you 
already know of this change.

* Q: Why didn't you do simply "mv vmlinux linux"?
R: because that way another "make linux" would relink again the files.
