Then you should use ausearch to find the AVCs over the time period when it ran, and pipe that into audit2allow. Hm, yes, thanks, I tried that ... Now I used ausearch -p to search by pid, and I might have found it. A selinux module was created with the output which would allow ejabberd to unlink files and directories of the appropriate type, and I installed that. I thought ejabberd deletes the files when restarting, but apparently it doesn't, so I'll have to watch for it in the log file. > HOWEVER... > > There’s probably a better solution than blindly creating a module. You need to figure out what the correct SELinux attribute to put on the directory so you don’t need a module. Yes, I did that. Perhaps the selinux permissions ejabberd is being installed with are incomplete.
