Bug description:
[Impact]
All new installs of 16.04.
[Test case]
1) Install Ubuntu 16.04 on a system
2) Validate that the size of the /boot partition is greater than or equal to 512MB; should be somewhere between 512MB and 1GB, close to 768MB.
[Regression potential]
This may adversely affect installs on tiny disks, by taking up more space for the /boot partition than was previously taken, at the cost of / or /home. As such, failures to install due to insufficient space on a partition, or failure to partition a disk that was previously working should be investigated as possible regressions.
This is a corner case in general since there is no requirement to allocate a separate partition for /boot in the default configuration, and if you are using a non-default configuration where /boot must be a separate partition, you probably also don't have a disk so small that an additional 256MB of disk usage is a problem.
---
The installer (in 16.04 and 17.10) creates a separate /boot partition,
when required, of only 487M. This ends up being rather small when you
using the following equation to estimate a minimal size allowing for
reasonable room for further growth.
(2*(3*kernel + 4*plymouth-carrying initrd + bootloader))
