[arch-general] permission problems with brasero (cdrecord)

[Łukasz Michalski]

Hi,

Today I discovered that I cannot burn CD from iso image with brasero - it says I do not have requires permissions.

My user is in "optical group".

I finally resolved this problem by setting sticky bit on /bin/cdrecord and /bin/cdrdao.

Is there a better solution?

Here is interesting part of log from brasero run with --brasero-media-debug --brasero-burn-debug --brasero-utils-debug:
