    Description

      Diving deeper into Funtoo From Scratch I would like to start building arm-64bit stage1s in preparation for generating custom metro arm64 stage3s.

      Tonight I hit this blocking error when trying to run an arm64-bit ffs build as both my regular system user and the root user:

      The initial ffs CLFS portion bootstrap succeeds, but I am getting the above error when fchroot starts up within the ffs lxc container

      I have read through all of the ffs docs, but I think I am completely missing something for ffs arm64-bit. Any help would be highly appreciated as I want to help with more rigorous testing of the ffs arm-64bit.
