Thanks for pointing this out. I just had a look at the spec file, and there are a couple of things that need changing before it can be used. I'll talk to the upstream maintainer about them. Okay. The permissions being set up in the %post section is a no-no: it means that 'rpm -V ...' will always fail, and that's bad news. And changing the permissions of files that the package doesn't even own is really nasty. The way it is supposed to work is that console users have the access that they need, rather than having a separate group for that. Otherwise it means changes in the cdrecord package, and other packages, etc. Plus, I think that this suits the vast majority of users, who don't know or care what groups are. However, I think that the console.apps file that makes this happen is wrong: it asks for root's password rather than the user's. That's easy to fix. As for the issue concerning the desktop file: this was changed for bug #50290. A fixed package has been built as xcdroast-0.98a9-3. New package, xcdroast-0.98a9-3, picked up from rawhide ftp site does not install: says libpng.so.3 is needed by xcdroast-0.98a9-3, which is provided by libpng-1.2.0-1.i386, again from rawhide. Attempted to upgrade libpng to latter version. Got multiple messages saying libpng.so.2 is needed by many different packages, this object in turn being provided by libpng-1.0.12-2, standard with RH7.2. Couldn't this xcdroast version be built against the current libpng distributed with RH7.2? You need to install both libpng10 and libpng to install rawhide packages that use libpng. libpng10 is the compatibility library, and libpng is the newer (but ABI incompatible) version. Did as advised above, re libpng10 and libpng -- and libpng-devel, for good measure . Started fine in root, but only from root login session. Would not start from su-ing to root in gnome terminal (non-login bash shell) from user session and executing xcdroast, complaining: Xlib: connection to ":0.0" refused by server Xlib: Client is not authorized to connect to Server. Same behavior if done from login bash shell. First start in user account, from console, got prompted for USER password (good!) but got error messages saying permissions on xcdrwrapper were wrong, with following message (although did start okay): ** WARNING **: The X-CD-Roast wrapper seems not to have the correct permissions set ** WARNING **: So do as root something like that: chown root:cdwrite /usr/lib/xcdroast-0.98/bin/xcdrwrap; chmod 2755 /usr/lib/xcdroast-0.98/bin/xcdrwrap ** WARNING **: For more information read /usr/share/doc/xcdroast-0.98a9/README.nonroot *** NOTE ***: --------------------------------------------------------------- This permission warning and the following set-uid bit warnings can be safely ignored, if you want to run X-CD-Roast as root only. --------------------------------------------------------------- Note: README.nonroot unchanged from prior version, still indicating change of ownership and permissions. Did chown root:cdwrite and chmod 2755 to xcdrwrapper. Started without permission/ownership warnings. However, I get the following messages: libpng warning: Application was compiled with png.h from libpng-1.0.12 libpng warning: Application is running with png.c from libpng-1.2.0 libpng error: Incompatible libpng version in application and library Have not yet attempted burn but seems to install and configure okay. Most of the errors are expected: xcdroast itself is running as root, and this is unfortunate. It's a side-effect of the console-user pam stuff. :-( The libpng warnings are to do with gtk---it needs to be recompiled against the libpng in rawhide, but it currently doesn't compile with the autoconf we have there. It'll be fixed before release, but the easiest work-around would probably be to downgrade to the xcdroast that came with Red Hat Linux 7.2 and replace the contents of /etc/security/console.apps/xcdroast with: USER=<user> PROGRAM=/usr/sbin/xcdroast SESSION=false I'll add a note to this report when the libpng problem has been resolved. I don't know if the problems are resolved, but I'm going to mark this as RESOLVED RAWHIDE, since the original problem is fixed. There are compiler things going on in rawhide at the moment so the package probably won't be much use to you (unless you are tracking _all_ of rawhide), but the work-around is detailed above. |
