            Bug ID: 228397
           Summary: freebsd-update: painfully slow on upgrades between
                    major versions
           Product: Base System
           Version: 11.1-RELEASE
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Many People
          Priority: ---
         Component: bin
          Assignee: bugs at FreeBSD.org
          Reporter: vermaden at interia.pl


upgrade from up-to-date FreeBSD 11.1-RELEASE-p10 to FreeBSD 11.2-BETA2 takes
forever ...

It took several hours ro fetch 45000+ (!) patches, then several hours to
install them and now several hours to finish the installation after the reboot
... and this is on a SSD drive ... imagine the same process on CLASS 4 SD card
with Raspberry Pi 2 ... ages.

IMHO current 'patches' approach is good for security updates (from p8 to p9 for
example) but its not suited for large upgrades like major version change.

IMHO HardenedBSD approach is better here (and magnitudes faster) with fetching
the whole new image and merging the differences.

If it would be me I would left current 'patches method' for minor updated
(between pX versions) and would import the HardenedBSD 'way' for major upgrades
like from 11.1-RELEASE to 11.2-RELEASE.
