Re: [Ltib] Problem using buildbot and --preconfig

[Stuart Hughes]

Hi Peter,

This is an strange one because it's clearly a permissions problem,
however normally for a query I would not expect you to need any root
permissions.

I just ran this (as my user) and no privilege was needed:

$ /opt/ltib/usr/bin/rpm --root `pwd`/rootfs --dbpath /var/lib/rpm -qa
--queryformat '%{name} '
base_libs dev zlib lzo tpt2000 lighttpd gmp .....

If I look at the permissions on that directory, I see this:

 ls -la rootfs/var/lib/rpm/
total 2588
drwxr-xr-x 2 root root    4096 2010-11-13 18:34 ./
drwxr-sr-x 4 root root    4096 2010-08-17 19:15 ../
-rw-r--r-- 1 root root  589824 2010-11-13 18:34 Basenames

-rw-r--r-- 1 root root   12288 2010-11-13 18:34 Requireversion
-rw-r--r-- 1 root root   12288 2010-11-13 18:34 Sha1header

So here's some ideas:

* You have some unexpected permissions in rootfs/var/lib/rpm

* Your auto-build environment has some kind of odd umask, or other
restricted user/environment

* Your rootfs area is NFS or something odd (a wild guess)

BTW: if you don't get anywhere, for a quick hack/test, you could put a
'sudo' at line 2022 to see if that changes behaviour.
