Package: mount Version: 2.41.1-2 Severity: normal Tags: upstream Hi,
I ran into this when configuring autofs direct mounts, which creates a trigger mount and the actual mount at the same mount point (whenever the auto-mounting triggers), so mounts may look like these, for example: $ mount | grep /mnt/tmp /etc/auto.direct on /mnt/tmp type autofs (rw,relatime,fd=9,pgrp=1582,timeout=300,minproto=5,maxproto=5,direct,pipe_ino=21088) tmpfs on /mnt/tmp type tmpfs (rw,relatime,inode64) First entry is the autofs trigger mount, with type autofs. The second one is the actual mount, triggered by changing the directory to /mnt/tmp. One may want to try and unmount the actual (tmpfs) mount using a command like this one, leaving the autofs trigger mount in place: sudo umount -t tmpfs /mnt/tmp However, if tmpfs is not currently mounted, then this command will also remove the autofs trigger mount, despite its type being autofs. This is unexpected behavior, which can also be disruptive, since removing the trigger mount will prevent future auto-mounting of /mnt/tmp from functioning properly, until the next reload of the autofs service. The potential fix appears to be a simple one, setting up of the types filter just needs to be moved out of the clause which is only triggered for --all: https://github.com/util-linux/util-linux/blob/master/sys-utils/umount.c#L624 This bug affects the trixie version of umount as well. -- System Information: Debian Release: forky/sid APT prefers unstable-debug APT policy: (500, 'unstable-debug'), (500, 'unstable') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 6.16.3+deb14-amd64 (SMP w/12 CPU threads; PREEMPT) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8), LANGUAGE not set Shell: /bin/sh linked to /usr/bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages mount depends on: ii libblkid1 2.41.1-2 ii libc6 2.41-12 ii libmount1 2.41.1-2 ii libselinux1 3.8.1-1 ii libsmartcols1 2.41.1-2 mount recommends no packages.
