Use getpwnam before getpwuid since two users with same uids can exists (affects new login classes code only) The same fixes as in inetd: by default run `system crontab things' with daemon login class now, not restrict them to user class breaking compatibility with old way (so-called nobody limits problem) Implement user[:group][/login-class] syntax in system crontab for more flexible control (the same as in inetd)
