bug#54969: "activate.scm.drv" Empty and Live

[Zain Jabbar]

Aloha Guix,

A number of errors have appeared on my system. Notably I have the following issue with "sudo guix system reconfigure $CONFIG_FILE":

"guix system: error: error parsing derivation `/gnu/store/8jqz1m1src0h4md70q09rlxppdy6d1jx-activate-service.scm.drv': expected string `Derive(['"

I believe this is due to key files on my system (e.g. "/gnu/store/...-activate.scm.drv" and "/gnu/store/...-activate-service.scm.drv") have become both empty and live on my system.

Here is the result of trying to repair using "guix gc"

"zjabbar@tao ~$ sudo guix gc --verify=contents,repair

It looks like a lot of files have the same hash and are empty. Is the only way to fix this to reinstall Guix? Is it known why this could happen in the first place?
