Where did that .pod end up? (sysdig)


So I RTFM yesterday and, not having any OpenSSL muscle memory, spelled it STACKOF in my program just like in the man page. Fail.

The .pod file was easy enough to fix, but does it format properly? What happens to it and where does it go?

$ sudo sysdig evt.type=open and fd.name contains cert_chain
(wait for command in other terminal)

$ make install_docs
...

That's more satisfying than strace since I don't have to run make install_docs under strace and decide how to separate their outputs. Now to use sysdig as often as possible for a while so I can get used to it...
