According to this bug
https://bugs.archlinux.org/task/67265
you can set up file capabilities on cdrecord binary during package creation or later
I set as root
setcap cap_sys_resource,cap_dac_override,cap_sys_admin,cap_sys_nice,cap_net_bind_service,cap_ipc_lock,cap_sys_rawio+ep /usr/bin/cdrecord
I have tried that setcap command, which seemingly solved the reported permission issues, but not the burning fail problems. I have also tried to setup K3b > Programs > Permissions as described on the Manjaro forum here https://forum.manjaro.org/t/k3b-can-t-burn-iso-image/3691 In my case: ls -la /usr/bin/cdrecord -rwxr-xr-x 1 root root 442160 nov. 23 2020 /usr/bin/cdrecord # chmod 4711 /usr/bin/cdrecord # chmod 4711 /usr/bin/cdrdao # chmod 0750 /usr/bin/growisofs # chown root:cdrom /usr/bin/cdrecord # chown root:cdrom /usr/bin/cdrdao # chown root:cdrom /usr/bin/growisofs # ls -la /usr/bin/cdrecord -rwx--x--x 1 root cdrom 442160 Nov 23 2020 /usr/bin/cdrecord # ls -la /usr/bin/cdrdao -rwx--x--x 1 root cdrom 646976 May 31 2018 /usr/bin/cdrdao l# ls -la /usr/bin/growisofs -rwxr-x--- 1 root cdrom 117792 Mar 31 2022 /usr/bin/growisofs At first K3b did not longer get access to the writer, then ran the setcap command again and got access. But unhappily, the BD-R/RE DL disc burning issues still appear.......
and it seems to work
# getcap /usr/bin/cdrecord /usr/bin/cdrecord cap_dac_override,cap_net_bind_service,cap_ipc_lock,cap_sys_rawio,cap_sys_admin,cap_sys_nice,cap_sys_resource=ep
