Here’s a clear, step-by-step guide to rebuilding libmount + mount (util-linux) from source on Void Linux. This is usually not required, but if your system is broken due to version mismatches, building from source can fix it.

✅ 1. Install build dependencies

#

You need the development tools and headers:

sudo xbps-install -Sy base-devel
sudo xbps-install -Sy pkg-config gettext-devel

Void Linux splits packages, so you also need required -devel packages:

sudo xbps-install -Sy util-linux-devel

If you’re rebuilding because util-linux is broken, the above command may fail — that’s okay, you can still build without it.

✅ 2. Download the latest util-linux source

#

Util-linux contains mount, umount, libmount, etc.

wget https://www.kernel.org/pub/linux/utils/util-linux/v2.41/util-linux-2.41.tar.xz
tar xf util-linux-2.41.tar.xz
cd util-linux-2.41

Replace 2.41 with the release you need.

✅ 3. Configure the build

#

Run:

./configure --prefix=/usr --disable-all-programs --enable-mount --enable-libmount

Explanation:

• --prefix=/usr → installs into /usr/bin and /usr/lib
• --disable-all-programs → disables everything except what you explicitly enable
• --enable-mount → builds the mount command
• --enable-libmount → builds libmount.so

✅ 4. Build it

#

make -j$(nproc)

This compiles mount and libmount.

✅ 5. Install (careful!)

#

This can overwrite system binaries. Safer method: install to a temporary directory first.

make DESTDIR="$HOME/mount-test" install

You’ll find new binaries in:

$HOME/mount-test/usr/bin/mount
$HOME/mount-test/usr/lib/libmount.so.*

Test them before installing system-wide.

⚠️ 6. Test without installing

#

Run the newly-built mount using an absolute path:

$HOME/mount-test/usr/bin/mount --version
ldd $HOME/mount-test/usr/bin/mount

Make sure it properly links to the newly built libmount.so.

⚠️ 7. If everything works, install to the system

#

Only do this if your current system is already broken:

sudo make install

🩹 If your system is badly broken

#

You may also need to temporarily set:

export LD_LIBRARY_PATH=/usr/local/lib:/usr/lib

Or override mount’s linked library:

LD_PRELOAD=/usr/lib/libmount.so.1 mount

🔍 Want easier debugging first?

#

I can guide you through:

• checking conflicting libmount versions
• verifying the /usr/lib symlinks
• using xbps to fetch the correct .xbps package
• reinstalling util-linux cleanly

If you want, tell me:

ls -l /usr/lib/libmount*
xbps-query -l | grep util-linux
mount --version
