[Bug translator/6925] New: make roland happy

[fche at redhat dot com]

See http://sourceware.org/ml/systemtap/2008-q3/msg00809.html

I see a few separate issues:

* running stap without a make install
  We could help by having the Makefile print out instructions
  about how to use stap from the build tree (for a make all)
  or the install tree (for a make install):

  % make
    [...]
    We recommend you "make install", but if you wish, you may
    run systemtap out of this build tree using these environment
    variables:
    env SYSTEMTAP_RUNTIME=......  

  % make install
    [...]
    We commend you upon your wise decision to install systemtap.
    You just need $prefix/bin in your $PATH and you're ready to enjoy.

  Yeah, the man page could help too.

* stap -r /BUILD/TREE should work better
  This is bug #5892, with some extras.  q.v.

* make verbosity a pass-dependent thing
  I don't know off-hand what to do ... maybe extend the "-p NUM"
  syntax to add an associated verbosity level for the duration.

* let stap find staprun and stapio in $PATH too
  The solution would be to extend $PATH with $prefix/libexec,
  or stat and execvp if $execdir/.../stap{run,io} don't exist.

* make staprun clean up before & after itself better w.r.t.
  loaded modules if something with stapio goes wrong

Please, not libexec, but $libexecdir from configure. It is /usr/lib/systemtap
on Debian.

could be an option like '--verbose-pass={1,2,3,4}' which would apply already 
set '-v' option only on the selected pass(-es, it could accept arguments 
separated via comma)

> * running stap without a make install

This is not a great idea.  git commit af29024 offers this advice:
configure: 
configure: For a private or temporary build of systemtap, we recommend
configure: configuring with a prefix.  For example, try
configure: ../systemtap3/configure  --prefix=/home/fche/systemtap-0.8-12350
configure: Running systemtap uninstalled, entirely out of the build tree,
configure: is not supported.

> * stap -r /BUILD/TREE should work better
>   This is bug #5892, with some extras.  q.v.

Fixed (better -r option).

> * make verbosity a pass-dependent thing

Fixed (--vp option).

> * let stap find staprun and stapio in $PATH too

Unnecessary if people are willing to follow --prefix advice.

> * make staprun clean up before & after itself better w.r.t.
>   loaded modules if something with stapio goes wrong

commit c94a9cb3 attempts to unload modules left over by a stap*
crash or SIGKILL, so that a subsequent stap run will work.
