I'm trying to use mock for the first time in order to do a package review. I've hit a few snags that I thought I should point out on this list. Let me know what I can do to help resolve them. First, the SHOULD item on this page: http://fedoraproject.org/wiki/Packaging/ReviewGuidelines that refers to mock should probably link to this page: http://fedoraproject.org/wiki/PackageMaintainers/MockTricks I have edit rights on the wiki, so if nobody objects I can make that change. As it was, I had to hunt for information on how to use mock. So I read the MockTricks page and the mock man page. MockTricks tells me to use '-r <config>' to select a config file. The mock man page says that if you don't select one, you get whatever /etc/mock/default.cfg links to. That's great, except that there is no such link as /etc/mock/default.cfg after installing mock. Should there be? If not, the text on the MockTricks page should perhaps be expanded a bit to note this and explain why not. Next I created the "build" user as described on the MockTricks page. Then I did "su - build", just like it says to do. It wants a password. The null password doesn't work. My password doesn't work. Fortunately, I am root on my box, so I can "su -" and then "su - build", but what is supposed to work here? I also noted that MockTricks says to do "mock rebuild <SRPM>", but the mock man page says that usage is deprecated. It's supposed to be "mock --rebuild <SRPM>" now. So I kicked off the mock build ... and setroubleshoot pops up to tell me about AVC denials. These are NOT the SELinux problems described on the MockTricks page. I got the following: 1) /usr/sbin/groupadd (groupadd_t) cannot "write" to /dev/null (var_lib_t). 2) /usr/sbin/groupadd (groupadd_t) cannot "ioctl" to /dev/null (var_lib_t). 3) /usr/sbin/useradd (useradd_t) cannot "ioctl" to /dev/null (var_lib_t). 4) /usr/sbin/useradd (useradd_t) cannot "read write" to (var_log_t). 5) /usr/sbin/useradd (useradd_t) cannot "write" to /dev/null (var_lib_t). I just updated to selinux-policy-3.0.8-58.fc8 shortly before installing and running mock. Are these failures expected? If so, MockTricks should warn me about them. If not, against what do I file a bug? So the mock build failed. I expected that, since I was pretty sure I had identified a missing BuildRequires. I went to the log files to verify that my guess was right, and found that build.log is empty. OK, so I'll try root.log. No sign of a missing BuildRequires there; but I do see some scary looking stuff: 2007-11-30 12:35:46,634 - DEBUG util.py, Line: 234: tar: ./usr/lib/locale/locale-archive: file changed as we read it 2007-11-30 12:35:46,638 - DEBUG trace_decorator.py, Line: 27: EXCEPTION: Command(tar czf /var/lib/mock/cache/fedora-8-x86_64/root_cache/cache.tar.gz -C /var/lib/mock/fedora-8-x86_64/root .) failed.

Likewise with the other directories on that list. How is this supposed to work? I hope we can work together to make this less confusing and frustrating for the next mock newbie.
