Hello.
If you are using an existing 7.0.1 after the version of the Synology DSM was updated to 7.1, you may want to update to 7.1
or this is a guide for those who want to install 7.1 from the beginning.
For those who are new to this article, I will share it with you by adding and subtracting it from the existing 7.0.1 guide.
It is a translation from Korean to English using a translator.
Please understand if there is a slight misunderstanding.
Ex
If you are using MSHELL and maintaining a FRIEND kernel, you can fix it by following the instructions below.
And in this topic, a lot of M SHELL-centered know-how has been accumulated.
Please use the M SHELL topic rather than this installation guide for now.
