Indeed, empty:
--8<---------------cut here---------------start------------->8---
$ file $(readlink -f
/gnu/store/1gd9nsy4cps8fnrd1avkc9l01l7ywiai-guile-3.0.9/lib/libguile-3.0.so.1)
/gnu/store/1gd9nsy4cps8fnrd1avkc9l01l7ywiai-guile-3.0.9/lib/libguile-3.0.so.1.6.0:
empty
--8<---------------cut here---------------end--------------->8---
However, I am not able to remove the item. I mean: I have tried many
operations as “guix gc”, “guix gc --verify” with ’repair’ and
’contents’, remove some part of ~/.cache/guix and then “guix gc”, remove
the complete ~/.cache/guix and then “guix gc”, rebuild the derivation
with --check, etc.
And the file is still empty. Arf, I spent some time to find which was
retained it.
Well, I did nothing special for that corruption. And once I had it, the
process for recovering is not straightforward. Somehow, it misses
helpers that maps item to profile.
For instance, in order to find the culprit retaining the item, I did
--8<---------------cut here---------------start------------->8---
$ guix gc --referrers /gnu/store/1gd9nsy4cps8fnrd1avkc9l01l7ywiai-guile-3.0.9
/gnu/store/1gd9nsy4cps8fnrd1avkc9l01l7ywiai-guile-3.0.9
/gnu/store/50vkm2fkk3aij8jc92phb3ahapn776m8-guix-command
/gnu/store/fd744pmbhzq1avpjjsmfiasp7yqdmiwy-guix-daemon
/gnu/store/vqkjfl6ds3vdvig2x5pkvvzkc3wivrp0-guile-wrapper
$ guix gc --referrers /gnu/store/50vkm2fkk3aij8jc92phb3ahapn776m8-guix-command
/gnu/store/fd744pmbhzq1avpjjsmfiasp7yqdmiwy-guix-daemon
/gnu/store/icp4z3cxp0fibsm4j887nz8k56jc1jgi-guix-7bf8b7c33
--8<---------------cut here---------------end--------------->8---
then ’grep’ the term ’7bf8b7c33’ inside /var/guix/profiles/per-user.
Well, it was retained because I did switch-generation. Anyway.
Hum, it could be nice if instead:
guix gc: error: cannot delete path `/gnu/store/…' since it is still alive
it would also point the “profile“ (or profiles) that makes it alive.
