   I can reproduce a package management failure caused by the perf mount on:

   WSL version: 3.0.3.0
   Kernel version: 6.18.54.1-1
   Distributor ID: Ubuntu
   Description: Ubuntu 24.04.5 LTS
   Release: 24.04
   Codename: noble

   Symptoms:

   sudo apt upgrade fails with:

   dpkg: error processing archive
   linux-tools-common_6.8.0-147.147_all.deb (--unpack):
   unable to make backup link of './usr/bin/perf'
   before installing new version: Invalid cross-device link

   Investigation:

   df -T /usr/bin/perf
   => /dev/sdb mounted on /usr/bin/perf

   findmnt /usr/bin/perf
   => /dev/sdb[/6.18.54.1-microsoft-standard-WSL2/perf/bin/perf]

   The mounted perf binary appears to shadow the file owned by
   linux-tools-common, causing dpkg hard-link creation to fail.
