just rooted my Remix mini as well
Just to clarify, the chinese guy you found didn't install busybox as there was a binary already present in Remix's system folder.
I tried to do it with the most recent UPDATE-SuperSU.....zip without any success. Instead, what i did was having a look into the update-binary shell file (META-INF/com/google/android/update-binary). Starting from line 59 there is a nice introduction on how to install all the needed files yourself. So in the end it is just alot of cp,chmod,chown and chcon typing. Keep in mind the Remix has an 64bit architecture.
Unfortunately i didn't record the whole process but this should give you an hindisght on how to do it yourself.
Files to be installed from zip:
common/Superuser.apk
common/install-recovery.sh
arm64/su (do different locations and with different contexts [chcon], don't mess this up)
arm64/supolicy
arm64/libsupol.so
target locations come from the update-binary file.
The next step is the real dangerous one! Don't do anything like this if you don't know what you are doing!
mv /system/bin/app_process64 /system/bin/app_process64_original
ln -s /system/xbin[or whereever you installed the su binaries]/daemonsu /system/bin/app_process64
After that you may run
/system/xbin/su --install (which in my case seemed to do absolutely nothing)
Really check that you have applied all the chcon['s] as in the update-binary file. Or else you may run into serious trouble (if /system/xbin/daemonsu doesn't have the context your system should not start anymore).
You can check the chcon['s] with ln -Z. If your file is not in the list, it doesn't have the context.
For a shorter list (e.g. /system/bin) you can also type like " ls -laZ app_* "
