This isn't like procfs. Although I first noticed this problem on 5.3, it is present on 4.10. >How-To-Repeat: With the standard line in /etc/fstab for linprocfs, run mount -a several times, then run mount. You will see an output like this: $ mount /dev/ad0s3a on / (ufs, local) devfs on /dev (devfs, local) /dev/ad0s3e on /tmp (ufs, local, soft-updates) /dev/ad0s3g on /usr (ufs, local, soft-updates) /dev/ad0s3f on /var (ufs, local, soft-updates) procfs on /proc (procfs, local) linprocfs on /usr/compat/linux/proc (linprocfs, local) linprocfs on /usr/compat/linux/proc (linprocfs, local) linprocfs on /usr/compat/linux/proc (linprocfs, local) linprocfs on /usr/compat/linux/proc (linprocfs, local) linprocfs on /usr/compat/linux/proc (linprocfs, local) linprocfs on /usr/compat/linux/proc (linprocfs, local) Note that the extra mounts can be umounted, one at a time, similarly. >Fix: Unknown. >Release-Note: >Audit-Trail: >Unformatted:
