bug#69401: /etc/guix/machines.scm symlink can be garbage collected
Some of the build nodes behind the Berlin build farm have a childhurd which can build packages. Unfortunately, the symlink from /etc/guix/machines.scm to the generated file in the store to setup offloading has been garbage collected on several of the machines. -- Efraim Flashner רנשלפ םירפא GPG key = A28B F40C 3E55 1372 662D 14F7 41AA E7DC CA3D 8351 Confidentiality cannot be guaranteed on emails sent or received unencrypted signature.asc Description: PGP signature
