New schemas aren't picked up by running gconfd-2 [was Re: rawhide report: 20060125 changes]

[Mark McLoughlin <mark skynet ie>]

Hi,
	Just a heads up to people here, it looks like switching to "merged
subtree" mode in gconf has seriousy exasperated the old "gconfd-2
doesn't pick up new schemas" issue.

	I've upstreamed the bug to here:

  http://bugzilla.gnome.org/show_bug.cgi?id=328697

Cheers,
Mark.

	Problem sounds like a gconfd-2 caching problem - i.e. gconfd-2 is
running as the user and doesn't notice when new schemas are installed.
There has always been the potential for that problem, but it can be much
worse now:

  - previously, gconfd-2 would have picked up schemas for newly 
    installed apps - it would be a new dir under gconf.xml.defaults 
    which wouldn't have been cached. It wouldn't have picked up new 
    schemas for an already installed app, if that app had been run and 
    the new schemas were in the same dir as the old schemas.

  - with "merged subtree" mode, though, schemas are added to one big 
    file which is going to be cached by gconfd-2 already. So, it's not 
    going to notice any new schemas

  - what's more, if you're running an old gconfd-2 and you update, then 
    the apps all install their schemas into the merged database and 
    gconfd-2 is still reading from the unmerged version.

	Doing the equivalent of "killall -HUP gconfd-2" from gconftool-2
--makefile-install-rule should fix it.
