I am not able to find menu.lst in /boot.
During the Linux Kernel Compilation I installed the kernel using make install.
Next I created an initrd image.
I had to modify the Grub configuration file - /boot/grub/menu.lst which I am not able to find.

pstack - print a stack trace for each LWP in each process and core file
SYNOPSIS DESCRIPTION
prints a stack trace (hex+symbolic) for each LWP (Lightweight Process) in each process and core file.
Given the pid of a running process or the full path of a core file, prints the stack trace for each LWP thread in the process. To obtain
symbol information, searches load modules (executable and shared libraries) in the current directory, and You can specify the executable
path with the pid/corepath, separated by a colon character. If cannot find a load module, symbol information for frames in that module is
not displayed.
works by attaching to the running process and reading its registers, memory, and stack. Mismatch between executable and corefile may
result in unpredictable behavior.
Options
supports the following option:
Prints the usage menu.
Operand
supports the following operand:
pid identifies a running process, with an optional execpath, the full executable path.
corepath is the full path name of the specified executable.
RETURN VALUES
