Hi
I am new to uml. At this time, I even can't use the kernel binary and image
to start uml.
I am using debian sid, the uml version is 2.6.18-1um-2: i386. My host kernel
is customized by myself, which is 2.6.19.2
And when I using binary kernel in
http://uml.nagafix.co.uk/kernels/kernel32-2.6.20.3 and busybox , I encounter
this:
VFS: Mounted root (ext3 filesystem) readonly.
: applet not found

I also tried compile by myself. But no advance.
Please help!
BTW: I spent hours to find a relative-stable kernel with UML to compile, but
found a lot of then can't be compiled because of a PAGE_SHIFT error and
syscall0 error. After fix these, I still can't run it up. So I change to
binary kernel, but failed again.
Thanks.
