Thanks for sharing all of that information.
The /init mount point is an implementation detail for WSL2. From
skimming Microsoft's article [1], it seems like it receives the requests
to start Linux and Windows processes, handling them accordingly.
The issue is that this file is listed as rootfs in /proc/self/mountinfo,
but statfs reports it as tmpfs:
$ grep --perl-regexp '\s+/init\s+' /proc/self/mountinfo /etc/mtab
/proc/self/mountinfo:111 82 0:2 /init /init ro - rootfs rootfs
rw,size=1982392k,nr_inodes=495598
/etc/mtab:rootfs /init rootfs ro,size=1982392k,nr_inodes=495598 0 0
$ stat --file-system --format %T /init
tmpfs
I'm inclined to leave 'df' as is, since the only way to detect whether
we are WSL is through heuristics which may change in future WSL
versions.
I've attached a patch to skip the test. Pádraig, okay to push or shall
I wait until after release?

I've pushed that now.
Marking this as done.
Thank you.
