Do you know what initramfs-kernel mean?
I know squashfs-factory/squashfs-sysupgrade.
How can I do it or what is it? which is better?

I just don't understand what the initramfs-kernel mean.
I have Linksys 1900ACS v2 and D-Link DL-860l B1, but I only use squashfs-factory and squashfs-sysupgrade.
What does the initramfs-kernel mean?
When would I use those?

I would even fear to install that.

So, continuing, like lede-17.01.2-ramips-mt7621-dir-860l-b1-initramfs-kernel.bin, what does this mean? can i use it and if so, what is the difference between lede-17.01.2-ramips-mt7621-dir-860l-b1-squashfs-factory.bin (which I know what it does and how) or lede-17.01.2-ramips-mt7621-dir-860l-b1-squashfs-sysupgrade.bin (which I know what it does and how).

The initramfs OpenWRT/LEDE kernel builds are including the rootfs image into initramfs, attaching it to the kernel so it will put the filesystem in a ramdisk during bootup and utilize it as /. You don't need such builds if the regular flash-based storage works for you, as it won't allow any persistent configuration by default. Such a configuration is useful during initial OpenWRT/LEDE porting efforts when you don't have the flash driver configured to use the flash chip on the device.

Initramfs kernel is like live os distro. You can test it without installing into the sd card. So, if you want to test the image initramfs is useful.

That image is the same as using the toram kernel boot command except its setup before hand for quickly tossing everything and the kitchen sink straight into ram.
