[gentoo-user] Installed vs. Running (new feature suggestion)

[Grant]

A while ago I posted a question to this list asking how to be sure
updated software has taken effect on your machine.  Gentoo makes it
easy to install updated software, but what about being sure the newly
updated software is actually running in place of the old version?  The
concensus seemed to be that there are really only two ways to do this:

1. know enough about the updated software that, if necessary, you can
run the appropriate commands to make it take effect

or:

2. reboot

Neither of these seem practical to me.  What about a new Gentoo
feature that either:

1. keeps track of what needs to be done for each update to take effect
and can report whether or not that has been done since updating
(probably not so good)

or:

2. reports what version of installed software is actually running and
it's up to the user to figure out what needs to be done if installed
and running software versions do not match (probably better)

What do you think?

A third way. Run (as root)

lsof | grep -i del

This will allow you to see which applications are using deleted files
(ie those that have been replaced). Then you just have to restart the
applications concerned.

bash: lsof: command not found.

I must be missing something

Have you emerged sys-process/lsof? The binary is in /usr/sbin/, so it
might not be in your path.

3. Whenever an ebuild installs a script in /etc/init.d, it checks to see
whether the service is already running. If it is, it sends an ewarn
message. Now that portage is able to mail these messages, they no longer
get lost in the reams of output from an emerge, so they are now genuinely
useful.

The severity of the itch is inversely proportional to the reach.

How do we do that?  "man emerge, man portage and man make.conf" dont
mention this.  Which docs should I be looking at?

/etc/make.conf.example

As it's only in ~arch portage at the moment, it doesn't appear to have
made its way into the man pages yet. I noticed the changes when running
dispatch-conf.

I've got a mind like a... a... what's that thing called?

Very nice.  Should that cover all instances of action needing to be
taken for an update to take effect?  It wouldn't handle kernel
updates, but that one is obvious.
