Hello,

I just compiled a test package and tried a
"guix gc -d /path/to/package/in/store"

After printing
 deleting `/gnu/store/642pwarg5hppzh1gwadd07w0g4w3rwpx-nss-certs-3.17.3'
 deleting `/gnu/store/trash'
 deleting unused links...
which is instantaneous, I need to wait for 5 minutes with the disk spinning.

I suppose this is a side-effect of deduplication?

Andreas

Literally 5 minutes?  It would be more like 30s on my SSD.

That, and the fact that you have a disk that actually spins.  ;-)

If you haven’t GC’d in a long time, it’s also likely to take longer.

Maybe that was the problem. I tried again later to gc one package, and it was
almost instantaneous. Which means that there might not be a problem after all.

OK, closing it then.

Thanks,
