There are 1,484 files affected by this commit - Is there a way I can narrow
this down even further within this commit?
Also attaching "strace -f" output from guest during execution of "zypper
dup" leading to hang, as well as corresponding qemu gdb log following
hang.
The last lines of the strace are:
