Public bug reported:
Imported from Debian bug http://bugs.debian.org/1147211:
Package: util-linux
Version: 2.42.3-1
Severity: normal
X-Debbugs-Cc: [email protected]
Hello there,
Something™ breaks in util-linux >2.42, likely in `libmount1`.
This was caught by the `squashfs-mount` autopkgtest in Ubuntu, because we do
run them with `isolation-machine` as opposed to Debian:
* https://ci.debian.net/packages/s/squashfs-mount/unstable/amd64/
* https://autopkgtest.ubuntu.com/packages/s/squashfs-mount/stonking/amd64
I didn't dig into the `util-linux` codebase, but here is a simple reproducer
script:
```bash
#!/usr/bin/bash
WORK_DIR=$(mktemp -d)
cd "$WORK_DIR"
mkdir -p folder
echo "Hello there" > folder/hello.txt
mksquashfs folder image.sqfs -quiet -noappend
mkdir -p mnt
squashfs-mount image.sqfs:mnt -- cat mnt/hello.txt
cd -
rm "$WORK_DIR" -rf
```
Run that in an Ubuntu Stonking VM against 2.41.3-3ubuntu2:
```
skia@kiffex:~
❯ lxc launch -e ubuntu-daily:26.10 ubuntu-stonking --vm
Launching ubuntu-stonking
skia@kiffex:~
❯ lxc shell ubuntu-stonking
root@ubuntu-stonking:~# apt update -qq

Hello there

ubuntu@ubuntu-stonking:~$
```
And the same against 2.42.3-1 on Debian unstable:
```
skia@kiffex:~
❯ lxc launch -e images:debian/sid debian-sid --vm
Launching debian-sid
skia@kiffex:~
❯ lxc shell debian-sid
root@debian-sid:~# apt update && apt install squashfs-tools squashfs-mount
[...]
root@debian-sid:~# useradd debian
root@debian-sid:~# su debian
$ bash
debian@debian-sid:/root$ cd /tmp
debian@debian-sid:/tmp$ vim reproducer.sh
debian@debian-sid:/tmp$ dpkg-query -W libmount1
libmount1:amd64 2.42.3-1
debian@debian-sid:/tmp$ ./reproducer.sh
[==================================================================================================================================================|]
1/1 100%
/tmp/tmp.fgOxcel9XK/mnt: can't find in /etc/fstab
/tmp
```
I left severity "normal" because technically, the Debian QA didn't raise
an eyebrow on the issue, so nothing is broken per say, but I would
consider raising the priority considering this is indeed breaking other
packages.
Let me know if you need anything else to help reproduce or debug.
Cheers
Skia
