Hi Guix,

Repeated invocations of `guix gc --verify=repair,contents` repeatedly
tries to repair the same store items, but they don't actually seem to be
repaired. My store is on btrfs and the btrfs tools seem to report a
healthy filesystem. I've attached the contents of one of the problematic
items.

Best,
Jack

Hi Jack,

nckx here. Thanks for reporting this bug, and thanks for including
information that might help fix it.

Unfortunately — another word for ‘base64’ — this makes your message a
whopping 20 MiB in size. We really can't send that out to all
subscribers, some of which might be on slow and/or expensive
connections.

That's all right: your report is still accessible at
https://issues.guix.gnu.org/54192, including the attachment. It's a
bit slow to render here but I think the extra info's worth it.

Kind regards,

T G-R
