# zypper in cdrecord
(8/8) Installing: cdrecord-3.02~a10-6.1.x86_64 
Additional rpm output:
setting /usr/bin/cdrecord to root:root 0755 "=
cap_ipc_lock,cap_sys_rawio,cap_sys_nice,cap_sys_resource+ep". (wrong missing
capabilities)

# l /usr/bin/cdrecord 
-rwxr-xr-x 1 root root 400848 Nov 18 23:36 /usr/bin/cdrecord
# getcap /usr/bin/cdrecord 
/usr/bin/cdrecord = cap_ipc_lock,cap_sys_rawio,cap_sys_nice,cap_sys_resource+ep

If k3b thinks this is insufficient permissions, it is a bug in k3b. mode 04711
