To complement what Liliana wrote, there are two kinds of GC root:
“regular roots” (the symlinks under /var/guix/profiles and
/var/guix/gcroots), and “indirect roots” (symlinks created when you run
‘guix shell’ or when you run ‘guix package -p ~/my-root’).
Indirect roots are invisible to the GC if the file system where they
live is inaccessible. That’s what you observed.
There’s no good solution I can think of, except not storing indirect
roots on a file system not visible to the GC.
I hope that makes sense!
Thanks,
Ludo’.
