Package: util-linux
Version: 2.39.3-6
Severity: normal
File: /usr/sbin/fsck

Dear Maintainer,

Just got
  [ 3030.473467] FAT-fs (mmcblk1p1): Volume was not properly unmounted. Some 
data may be corrupt. Please run fsck.
great idea! After unmounting I did
  # fsck /dev/mmcblk1p1
  fsck from util-linux 2.39.3
which is just --version. Maybe
  # fsck -AR
  fsck from util-linux 2.39.3
so also no.

which looks like a failed path traversal and then nothing?
So fsck just happily exited 0 with no warnings for my potentially-broken
filesystem, which I'd classify as "not very cash-money".

Best,
