The growfs_fstab script has been testing dumpdev, and if it is AUTO, enables dumps on the newly-added swap device for the initial boot. However, dumpdev defaults to AUTO on main, but NO on stable/13 and release branches. On the other hand, bsdinstall adds dumpdev="AUTO" by default (controlled by a menu item). bsdinstall is not used when booting an SD card or other disk image. Adopt the default from bsdinstall, and set dumpdev to AUTO in /etc/rc.conf in the growfs_fstab script if a swap partition has been added, along with the explanatory comment added by bsdinstall.
