Description of problem:
SELinux is preventing /usr/bin/gs from 'create' accesses on the file _______.pdf.

*****  Plugin catchall (100. confidence) suggests  ***************************

If 您認為 gs 就預設值應擁有 _______.pdf file 的 create 存取權。
Then 您應將此回報為錯誤。
您可產生本機模組,以允許這項存取。
Do
現在透過執行以下指令來允許此存取:
# grep gs /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Comment 1 Daniel Walsh 2013-07-01 10:55:35 UTC
Very strange, you should not have gotten this avc

   type_transition cups_pdf_t user_home_dir_t : file user_home_t;  

Since we have these rules in policy.

This says that if cups_pdf_t tries to create a file in a directory labeled user_home_dir_t, it will get created as user_home_t.

At least in F19.

Miroslav are we missing these rules in F18?

Comment 2 Miroslav Grepl 2013-07-01 11:13:53 UTC
There was a different trans rule. Fixed.
