Description Lukas Slebodnik 2015-11-06 13:38:16 UTC 
Description of problem:
If tmpfs plugin is enabled then it is harder to find issue with installation of basic packages in chroot. Because the root.log file does not contain any messages. So it is not clear what failed.

Version-Release number of selected component (if applicable):
mock-1.2.13-2.fc22

How reproducible:
Deterministic

Steps to Reproduce:
1. Enable tmpfs plugin in mock configuration
sh# cat >> /etc/mock/site-defaults.cfg <<EOF
config_opts['plugin_conf']['tmpfs_enable'] = True
config_opts['plugin_conf']['tmpfs_opts']['required_ram_mb'] = 1536
config_opts['plugin_conf']['tmpfs_opts']['max_fs_size'] = '1536m'
EOF

2. Try to rebuild some pacakge
wget https://kojipkgs.fedoraproject.org//packages/sssd/1.13.1/4.fc24/src/sssd-1.13.1-4.fc24.src.rpm
mock --rebuild sssd-1.13.1-4.fc24.src.rpm --resultdir .


Actual results:
root.log does not contain details about installation of basic packages in chroot.
e.g. Executing command: ['/usr/bin/dnf', '--installroot' ... 

Expected results:
The similar output as without enabled tmpfs plugin.

You can try to see differences between attached file.
diff root.log root_tmpfs.log
Comment 4 Miroslav Suchý 2015-12-22 00:34:33 UTC 
Hmm I see:
  ['/usr/bin/dnf', '--installroot'
in both files exactly 6 times.

The diff is hard to read and there are differencies in paths so it is quiet verbose.

Can you please clarify which lines exactly you are missing?

Note: we are using tmpfs plugin in Copr and I did not notice any missing part in logs.
Comment 5 Lukas Slebodnik 2016-03-08 14:34:19 UTC 
I'm sorry for replying so late. It was not a big priority for me. 
I could not find installation of "@buildsys-build" in root_tmpfs.log
But now I realized that it was caused by already created root cache log.
/var/cache/mock/fedora-*-x86_64/root_cache/

I agree it's not a bug.
