:*****  Plugin catchall (100. confidence) suggests  ***************************
:
:If you believe that chkconfig should be allowed getattr access on the systemd file by default.
:Then you should report this as a bug.
:You can generate a local policy module to allow this access.
:Do
:allow this access for now by executing:

Comment 1 Miroslav Grepl 2012-03-09 11:58:00 UTC
Why does s-c-samba use chkconfig instead of systemctl?

Comment 2 Daniel Walsh 2012-03-09 14:33:01 UTC
Does not seem like something we should block.

> Why does s-c-samba use chkconfig instead of systemctl?

Probably because of the old codebase... I have a piece of code to abstract SysV and systemd services lying around in s-c-date which I'll add to s-c-samba.

    don't run chkconfig on systemd service units (#801740)
    
    Copy and use service abstraction classes from system-config-date.

I've just tried this out with this version of s-c-samba, both smb and nmb services disabled and stopped. I straced both the frontend and backend (mechanism) programs and found no indication that s-c-samba called chkconfig for any reason. Would you please strace this and check if this is somehow different with you? The commands are:

As root:

strace -Ff -e execve -o /tmp/scsamba-mech.out /usr/share/system-config-samba/system-config-samba-mechanism.py

--> leave it running

As user:

strace -Ff -e execve -o /tmp/scsamba-ui.out /usr/bin/system-config-samba



Try to reproduce the issue and attach the resulting files /tmp/scsamba-mech.out and /tmp/scsamba-ui.out to this ticket. Thanks!
