Shameless self-promotion: also take a look at https://github.com/u-root/u-root :)

(The gokrazy and u-root people all work at Google, I just contacted them to see if we can help each other. Not a competing project.)

Any relation to https://github.com/u-boot/u-boot ?

No, what sigjuice said is right. The name was derived off u-boot, though, and u-root can be used (and is in use) with LinuxBoot.

Doesn't look like it. U-boot is a boot loader for PowerPC/ARM/MIPS/<other CPUs> boards. A typical Linux-based embedded system would consist of U-Boot, the Linux Kernel and a filesystem. u-root would be one of the many ways to construct this filesystem.
