Permissions and errors in cronjob

[manics]

A recent update on a server that uses this role led to the following cron errors:

/etc/cron.daily/logrotate:

error: Ignoring osad because of bad file mode - must be 0644 or 0444.
/etc/cron.daily/mysql-backup:

 /usr/bin/mysqldump: Can't create/write to file '/xxx-Wed.mysqldump.tmp' (Errcode: 2 "No such file or directory")
stat: cannot stat ‘xxx-Wed.mysqldump.tmp’: No such file or directory
/etc/cron.daily/mysql-backup: line 8: [: -lt: unary operator expected
mv: cannot stat ‘xxx-Wed.mysqldump.tmp’: No such file or directory

• change the permissions on /etc/cron.daily/mysql-backup
• Add set -eu to the script
