Hiya Guix,

I imagine many folks are aware of this outcome, but from a quick search of
the archive I didnt find a discussion.

I decided to create a new user for building the lighter profile to deploy
in Singapore. Not knowing beyond the surface of how user profiles operate
at the Linux level, I changed my user name in my config without adding a
new user, thinking that only building a system with one profile will be
faster (with the servers having problems I'm having to fallback quite a
bit, so every bit of time saved helps)

But when I run $guix system roll-back, the account is broken. If I set the
password again as root and then try to log back in, it crashes during
loggin and in returned to the login menu. If I try to login with $sudo su
blake2b, I get the error: Permission denied: /home/blake2b/.bashrc. if I
remove  bashrc and then try to continue, the error happens again. And its
the same if I reconfigure with the new user.

So it seems this is a corner case of somewhat severe non-reproducibity (you
can't even access the environment). I'm guessing it has something to do
with setuid, perhaps the access rights are given to a strictly different
user even if the name is the same.

Is there any fix to this?

Ez,
Blake
