Description of problem: With system-config-printer-0.7.50-1.fc6 from updates-testing hitting "Apply" after picking and setting one or more job options makes them all just vanish. This is not a question of only display. There are no changes to be noticed in any files in /etc/cups/ directory too. What is more interesting is that system-config-printer-0.7.50-1.fc7 on a rawhide installation does not behave that way although in other details it is very similar. Well, there is at least one difference. Hitting "Make Default Printer" button in "Settings" does no cause here any complaints (see bug 227936). It appears that action only writes a new classes.conf which, at least in my case, does not differ from classes.conf.O save a recorded in it date. Version-Release number of selected component (if applicable): system-config-printer-0.7.50-1.fc6 How reproducible: always
What do these commands say?: /usr/sbin/getenforce ls -Z /etc/cups
Ah, a very good guess. Thanks. '/usr/sbin/getenforce' says "Enforcing" and there was "system_u:object_r:file_t" on printers.conf. After I changed that to "system_u:object_r:cupsd_rw_etc_t" job options started to behave. OTOH this silent disappearing act was really mystifying.
