Hi, all!
vdsm-logrotate kept reporting errors like "error: skipping "/var/log/core/core.3150.1321682189.dump" because parent directory has insecure permissions (It's world writable or writable by group which is not "root") Set "su" directive in config file to tell logrotate which user/group should be used for rotation."
This was caused by setting /var/log/core world-writable in vdsm.spec.in. After I simply added "su root root" to the /var/log/core/*.dump rotation configuration, it seems to be solved now.
So is this the way to fix the problem? Or any better else?
That is probably the correct solution - logrotate has recently changed to improve security. From Debian's /usr/share/doc/logrotate/NEWS.Debian.gz:
logrotate (3.8.0-1) experimental; urgency=low
Please note that this update changes the behaviour of logrotate:
Logrotate now skips directories which are world writable or writable by group which is not "root" unless the (new) "su" directive is used.
