Harmen Stoppels c300b92047 environment: be more defensive when deleting roots for old views (#29636) ... Currently `old_root` is computed by reading the symlink at `self.root`. We should be more defensive in removing it by checking that it is in the same directory as the new root. Otherwise, in the worst case, when someone runs `spack env create --with-view=./view -d .` and `view` already exists and is a symlink to `/`, Spack effectively runs `rm -rf /`.		2022-03-23 08:54:55 -06:00
