>Description:
The man page for newsyslog only states that it checks file size and not disk usage for whether or not to move a log file.  When newsyslog runs it looks at the number of blocks used and not the file size.  Given that the intent could be different for different sysadmins, I am not sure if it would be a software bug or a documentation error.
>How-To-Repeat:
Use zfs for /var/log with compression enabled, run ls -lh and see file sizes larger than configured in /etc/newsyslog.conf.
>Fix:
It's either a coding error and documentation ambiguity.
