ktrace(8); you can use it to trace all descendants of 'init'.
Looking at the man page it's non-obvious how to use it (to me).
Specially it seems one needs to indicate a pid or a command. How do I
trace all programs?
Maybe you provide the init pid, and the -i option. I played with this a
bit last night, and found out I really love this tool! Here's what I
did to play with it:
(find pid of a bash shell running - was 1268)
In another shell:
ktrace -tni -ip 1268
In ktraced shell:
cd /
cd /tmp
touch t
cat t
rm t
In ktrace shell window:
ktrace -C
kdump | less
That should give you a quick idea how to use it. The man page is pretty
decent.
