On https://openwrt.org/toh/ubiquiti/ubiquiti_edgerouter_x_er-x_ka there is an explanation of how to install OpenWRT on an EdgeRouter X using the tools that are standard installed on it and are used by Ubiquiti to upgrade the firmware. It seems as part of the build process a openwrt-ramips-mt7621-ubnt-erx-initramfs-factory.tar file is generated that can be used for that. But it seems you can not download it from the official site, you need to build it yourself. On the official site is an openwrt-18.06.1-ramips-mt7621-ubnt-erx-initramfs-kernel.bin file. I think that file can be used for installing using tftp, but it can't be used with the Ubiquiti tools. Can the initramfs-factory.tar be made available to download?

It seems that image generation failed due to "initramfs kernel image too big".

WARNING: initramfs kernel image too big, cannot generate factory image

[[http://release-builds.openwrt.org/18.06/images/builders/ramips%2Fmt7621/builds/144/steps/images/logs/stdio|buildlog on official buildbot]]

The size of official image "openwrt-18.06.1-ramips-mt7621-ubnt-erx-initramfs-kernel.bin" is 3,428,783 bytes, but it must be less than 3,145,728 bytes in order to generate initramfs-factory.tar.

Indeed, that image has been too big to be built for a long time; however, the initramfs image has to be built with the same settings as the other images.

There is no trivial solution to this.
