Subject: [PATCH] Log RPMLOG_ERR level messages on actual errors in selinux
|
|
|
0b2921 |
plugin, doh.
|
|
|
0b2921 |
|
|

When there's an actual error, people will want to know without having
|
|
|
0b2921 |
to rerun in verbose mode. Such as in RhBug:1641631 where configured
|
|
|
0b2921 |
selinux policy differs from what is installed - the former message
|
|
|
0b2921 |
|
|
|
0b2921 |
error: Plugin selinux: hook tsm_pre failed
|
|
|
0b2921 |
|
|
|
0b2921 |
...is not particularly helpful to anybody, whereas this actually provides
|
|
|
0b2921 |
some clues now:
|
|
|
0b2921 |
|
|
|
0b2921 |
error: selabel_open: (/etc/selinux/ponies/contexts/files/file_contexts) No such file or directory
|
|
|
0b2921 |
error: Plugin selinux: hook tsm_pre failed
