[Buildroot] [PATCH] modem-manager: now needs libgudev under systemd

[Vicente Olivert Riera]

Dear Yegor Yefremov,

when you say that "modem-manager: now needs libgudev for systemd", what
do you mean exactly by "now"? I would expect something like "since
version X" or a better explanation.

I know you are trying to keep all the depends together and all the
selects together, but since this is not related with the goal that your
patch is trying to achieve, I would do it in a separate patch.

Perhaps an explanation like the one included in this patch would useful
to understand why libgudev is needed:

Well, I think you're being a bit too picky here. It is indeed nicer
when the information is more specific, but since there is a clear
autobuilder failure, I think Yegor's commit log is good enough. Better
is better, for sure :-)

While I do agree that separating logical changes into separate commits
is important, we shouldn't be too zealous about that either. So I'm
personally fine with such small (but related) side changes. It's better
when the commit log contains something such as:

While at it, group the existing dbus select together with the dbus-glib
select, so that all "select" statements are together.

Best regards,

Thomas

So. I've sent v3. Patch description provides the whole story and if
someone will want to know, why BR2_PACKAGE_LIBGUDEV is selected, he
can use "git blame".
