Public bug reported:
PROBLEM:
On install, the boot partition has the size 244.0 MiB or 499,712 sectors
SYMPTOM:
This causes apt-get upgrade to fail at a later time with messages like:
apt-get --yes dist-upgrade
…
update-initramfs: Generating /boot/initrd.img-4.4.0-57-generic
gzip: stdout: No space left on device
E: mkinitramfs failure cpio 141 gzip 1

dpkg: error processing package linux-image-extra-4.4.0-57-generic (--configure):

dpkg: dependency problems prevent configuration of linux-image-generic:

Errors were encountered while processing:
linux-image-extra-4.4.0-57-generic

E: Sub-process /usr/bin/dpkg returned an error code (1)
- status code: 100
FIX:
usually want multiple of 2,048 sectors / 1 MiB
One kernel revision is 56 MiB
Miscellaneous files is 28 MiB
File system overhead is 11 MiB
Typically there are 3 kernels: is the running, the latest and the second to
latest
56 * 3 + 28 = 196 MiB
A system upgrade requires 120 MiB free
So /boot should be at least 196 + 11 + 120 = 327 MiB in 1 MiB increments
A power of 2 would be 512 MiB or 1,048,576 sectors
