Oops! I didn't consider that. A solution (requiring changes to cdrecord) would be to make some settings in /etc/default/cdrecord mandatory without the ability to override them on the command line.

Qt, OpenGL and valgrind

kpilot and kalendar/kab conduits
I'm just curious, is anyone using kpilot and its conduits for
kalendar/kab with recent builds of kde? I stopped looking at using this
as an option a LONG time ago, as it was always marked as alpha-quality,
and seems to still be so, and never actually worked for me.
What I'm looking for is the same type of functionality that evolution
offers, in that I need some piece of software that will sync with my
palm pilot (IIIc), and sync in both directions with an address book and
a calendar manager. I know that when last I looked at kpilot and its
conduits, there were some HUGE problems with syncing things both ways,
from what I read. Granted, as I said, it never would sync in even one
direction for me, as the conduits crashed every time I tried to use
them. But from what I remember, there was no back-end design to
kalendar/kab such that making changes/deletes in kalendar/kab were ever
successfully carried over to the palm pilot.
Is anyone using this combination successfully now? Is there hope for
the near future that this will work as well as evolution does now?

But you do not really want that to users,you cannot trust ultimately, because suid-root in this case allows it to specify anything as dev= in cdrecord command line: overwriting any scsi device is nice for harmful things... The thing for cdrecord is, that it cannot use /dev/ but needs really raw access to the device (I hope this to come in kernel 2.6) because the sg* devices do not allow this. THATs the reason why it has to be setuid-root and it is really a kernel thing to change that. Using ATAPI-CDRWs is already possible (special kernel versions and a cdrecord patch is needed IIRC). On-top-of-cdrecord programs like XCD-Roast then approach the whole thing wrong: there is no need for them to be setuid-root when the cdrecord binary already is. But as this is not always the case (see above why maybe not), again they have to have root rights to call cdrecord. After all, the situation is there due to a lack of kernel abilities.

Right but a daemon is much more flexible how do deal with authorization and access rights.

You, as a user wanting to burn CDs, don't need any root privileges. The kernel is just fine. As is cdrecord. Your distribution (debian) or your administrator (that may be yourself) has to configure things properly and everything works just fine with ordinary user privileges. This may mean, that some programs have to run setuid root. That's not radically different from what's happening with other packages. If you're compiling some program yourself, don't expect it to do everything correctly out of the box. K3b, for instance, comes with its own setup tool. That's well-intended, but doesn't work hand in hand with debian configuration tools.

KDE 3.0.4 ate my fonts
Hi all, I have a minor but very annoying problem: I'm running woody, and until recently I had KDE 3.0.0 running perfectly on it (mostly due to advice gleaned from this very list). Yesterday I upgraded to KDE 3.0.4 by putting deb http://download.uk.kde.org/pub/kde/stable/latest/Debian/woody ./ in my apt sources and installing all updated packages. Everything's working fine except my TrueType fonts - they are all installed fine according to Control Center -> System -> Font Installer, but are not found in Control Center -> Look & Feel -> Fonts. Mozilla can find the fonts and anti-aliases them as it should, but KDE it seems cannot. My 3.0.0 had lovely anti-aliased TrueType fonts and I want them back! Anyone else had this problem and can offer some advice? Thanks in advance, Richard Boyce Linux Post-Newbie IT Officer, Fitzwilliam College, Cambridge.
