Yes, I am fine with this. Its actually not so bad. Most of the time its
only the beginning that little time (few days) needs to be invested but
returns are totally worth it. Also, this way I am able to find out the
broken packages as well which usually do not get reflected till a binary
exists in the store.

VM with guix installed would not be so useful. I am just stuck at the older
glibc. I will manage with whatever I have using Nix 17.03 release which
seems to still work but for my home machine I will continue to explore
guix.

Thanks again for quick response. I now understand where I stand what are
the actual problems. We can close this thread now.
