hi:
Are some signal handles added in the UML kernel ?

in the host kernel by system calls which are provided by the host
kernel,won't they?
By which ,the UML kernel have something with the host kernel?
Is it right?

I don't think you'll get much help with something as old as 2.4. I
haven't touched 2.4 in year

My hosts (100) are all running 2.4.35 with skas3 and all UML patches.
My UMLs (guests) are all running
2.4.35 with all UML patches. I'm testing OSPF and PIMD (within the

BSRs (PIMD) are fine. On
