K3b Error 254---x Cdrecord is not being run with root privileges.

Mon Mar 7 04:57:54 UTC 2005

Hi All,

got this error number, whilst attempting to burn an iso image to a cd-r 
disc in K3b. This time, on my work pc, where K3b has successfully 
written b4. Now, I could un this if it was the 1st time, which happened 
on a new, over the weekend, install of FC3, but, this work PC, also FC3, 
had no problems writing using K3b, and never got an error message about 
not being as root. Little confused, to say the least. Anyone got an idea 
on this.? 1st time was using cd media I'd used b4, successfully, albeit, 
on other machines. 2nd time, new media. Cheers.

Mark Sargent.

x unknown error 254

(Same error as I got on my home PC. K3b on both systems were installed 
via yum)
