A configuration file is different to the one currently installed. I would use the command line and use diff egConfiguring auto-unprotect.
Collected errors:
* resolve_conffiles: Existing conffile /mod/etc/anacrontab is different from the conffile in the new package. The new conffile will be placed at /mod/etc/anacrontab-opkg.
Finished installation...
So, is this something to be concerned about?
diff /mod/etc/anacrontab /mod/etc/anacrontab-opkg
to find out what is different.
