The release bundle CI seems to still be broken. Let me see if I can create a patch to fix that.

By the looks of the df output it seems that #2674 did not actually yield any additional free space. Trying to debug this in #2704. (In CBMC's CI we do gain approximately 30 GB of memory via such removal.)

I believe #2704 actually does the trick. See the (updated) PR description over there.
