Owl OpenVZ template - strange network configuration

I normally use my own package for init scripts, so... my apologies for
late discovery.

--hostname ovz-test.lan

This is not specific.  What exactly did you install from CD?  What did
you try updating it to?

Anyway, a few days ago I tried updating an Owl system installed in 2009
(that is, pre-3.0) to Owl-current (i686).  "make installworld" worked
just fine.  The issue that you reported did not occur.

Thank you for reporting this.  This file will now be preserved (starting
with next Owl-current snapshot).

IIRC, this is vzctl scripts' workaround for some Red Hat distro's
networking startup scripts.  I don't know if our current scripts need
this workaround or not - probably not.  I suggest that we don't waste
time changing this until we've updated to new vzctl.

The plan is to get the current/ancient network startup scripts that
we're still using committed directly into our native tree and then to
clean them up.

RE: Error in installworld

Dear Alexander,

Thank you for help! Now my kernel have built and I use it perfectly. 
According installworld - it was not critical error because all packets have installed successfully in
spite of this message. 
Thanks a lot!

New kernel

What is your reason to build from source rather than use our RPMs?
(Building from source is no problem if you prefer.  I am merely asking.)

This is the version we currently use, yes.  However, please don't forget
that we also apply the Owl patch on top of this.

> Anyway I`ve got error when compiling:

This suggests that you did not apply the Owl patch (from our native
tree).  Please do.  This is mentioned in the instructions on the wiki.

Also, please start with our dot-config-* (the appropriate one) and make
your desired config changes relative to that (keeping most other
settings intact).  (Maybe this is what you were doing already.  I just
thought I'd remind.)
