This is due to pmount calling mount -o atime (among other options) to mount a filesystem. But -o atime is broken on util-linux 2.39. This bug is easily reproduceable with
# mount -o atime /dev/sdd1 /mnt mount: /mnt: not mount point or bad option. dmesg(1) may have more information after failed mount system call. # mount /dev/sdd1 /mnt # It just got fixed in the upstream repository, but is not included in the 2.39.2 release: https://github.com/util-linux/util-linux/commit/2b99ee2526ae61be761b0e31c50e106dbec5e9e4 Ingo -- const_cast<long double>(Λ)
