This is the first time GC runs since we’ve increased the threshold from
10 TiB to 15 TiB free. There are at least 5 more TiBs to delete than
usual, so it’s expected to take more time.
Still, I’m surprised a mere ‘rm -rf’ can take this long. ‘strace -T’ on
the child guix-daemon process doesn’t reveal anything obviously wrong,
pause times or similar.
