From the ticket (see URL above).
Here's the details.
The default /boot partition is 200MB, but there's some overhead:
Ext3/Ext4 overhead: 7MB
Reserved space: 10MB
F11 kernel: 8MB (at least - usually 3 kernels = 24MB)
GRUB/EFI files: 1MB
Total overhead: 26MB
So there's 174MB of usable space maximum, and usually 158MB available.
preupgrade now requires at least 167MB free space on /boot:
F12 installer images: 143MB (8mb larger than F11!)
F12 kernel: 18MB (10mb larger than F11!)
RPM/anaconda tmpfiles: >=8MB (measured in stupid tests)
Total: 167MB (Was 149MB in F11 - no problem!)

There are definitely workarounds available, but none that meet the
criteria for preupgrade as an effortless upgrade option.
Thanks,
James
