For reference for HN users who don't know who this is:
> Greg Kroah-Hartman is a major Linux kernel developer. As of April 2013 he is the Linux kernel maintainer for the -stable branch, the staging subsystem, USB, driver core, debugfs, kref, kobject, and the sysfs kernel subsystems, Userspace I/O (with Hans J. Koch), and TTY layer.
I think it's fair to say he's the number two guy in the kernel. Is he younger than Linus? I could see him running the show when Linus has enough and calls it a day.
What is probably meant is "find easier to deal with" (hence the quotes around "manageable"). I'm only guessing, though - but in any event, let's not forget that not everyone around here is a native speaker of English! I can relate to the fact that it's sometimes difficult to express exactly what you have in mind.
I was very fortunate to have a conversation with him a few years ago. We talked a bit about his journey and a bit about his hacks, his setup, and of course a lot about Linux:
