bug#44735: gilbc of the running system got wiped while building a package, system broken

[Stefan]

Hi!

I resolved the problem by copying 
gnu/store/cb88z63hyg1icd2kkahiink2p291mhr2-glibc-2.31 from 
https://alpha.gnu.org/gnu/guix/guix-binary-1.2.0rc2.aarch64-linux.tar.xz into 
gnu/store on the NFS server. The system is running again.

Now I retried my commands and I am able to reproduce the problem:

stefan@guix ~/development/guix$ /home/stefan/development/guix/pre-inst-env guix 
build -L /home/stefan/guix u-boot-rpi-3

This is now the diff of a correct cb88z63hyg1icd2kkahiink2p291mhr2-glibc-2.31 
and the now broken one:

Indeed there are the hidden .nfs files leading to the unlink error.
If I would try the same commands a second time, as before, then more files will 
be removed and my system will brake again.

Why is guix trying to reinstall 
/gnu/store/cb88z63hyg1icd2kkahiink2p291mhr2-glibc-2.31? It is part of the 
running system already.


Bye
