[gentoo-user] trouble installing cups

[gottlieb]

When I reinstall CUPS /etc/cups/cupsd.conf is *not* updated.
Details follow.

Cups was behaving badly: the web interface could not be used.  The
browser would quickly say no process was listening on localhost:631

I compared cupsd.conf to the same file on another working system and
noticed the following differences

  1. *Many* pairs of lines were missing.  The first line of each pair
     was blank; the second a comment.  Presumably this has no effect.

  2. The initial block comment was missing.  Again no effect.

  3. One very influential change
       Listen localhost:631
     was replaced by a second copy of
       Listen /run/cups/cups.sock
     When I manually put back localhost:631
     the cups web interface again behaved normally.

  4. The following block was *added* at the end
        JobPrivateAccess default
        JobPrivateValues default
        MaxLogSize 2000000
        SubscriptionPrivateAccess default
        SubscriptionPrivateValues default

     The first, second, fourth, and fifth generated "Unknown directive"
     messages in /var/log/cups/error.log

So I reinstalled cups but /etc/cups/cupd.conf was not changed and still
has its old date and contents.  The merge looks clean (output below)

I am wondering if there is something wrong with my setup.
I have the userpriv feature enabled.

Any help would be appreciated.
thanks,
allan

/etc/ is CONFIG_PROTECTed. Also, portage knows if you are reinstalling
the same version of the same package and does not try to update the
configs again. To change this, run the emerge with --noconfmem and then
run *-update.

This part I knew, but would have expected to hear that config files
have new versions

That is what I missed.

Works perfectly.

You would if upgrading. But you are reinstalling the same version so
portage assumes you have already dealt with any config updates and don't
want to be bothered again. 

Remember when we had to go through loads of updates over again when
revdep-rebuild rebuilt a package with lots of config files. This avoids
that behaviour, --noconfmem brings it back.

Understood.  Thanks for the explanation.
