When looking at strace for various Guile things, I'm seeing a lot of
readlink system calls for directories in the load path, e.g.

readlink("/gnu", 0x7fff8738f430, 1023)  = -1 EINVAL (Invalid argument)
readlink("/gnu/store", 0x7fff8738f430, 1023) = -1 EINVAL (Invalid argument)
readlink("/gnu/store/lkx2k8hy40a6s3vz94287g8fr2sxs7h0-profile", 0x7fff8738f430, 1023) = -1 EINVAL (Invalid argument)

Any idea what leads to this behaviour?

Thanks,
