Description Enji Cooper freebsd_committer freebsd_triage 2014-11-20 08:26:26 UTC
The handbook and manpages for linprocfs/linsysfs don't describe how linprocfs/linsysfs should be mounted via /etc/fstab. I used the following incantation and it worked with mount -a after the kld's had been loaded and my CentOS 6.x base had been installed.

  linproc /compat/linux/proc      linprocfs rw,late    0       0
  linsys  /compat/linux/sys       linsysfs rw,late     0       0

I found this in the linprocfs(5) man page, though I can't be certain it was there when you sent this in!
Comment 2 Alexis Praga 2021-01-13 18:49:15 UTC
This is also mentioned in emulators/linux_base-c7. In short : 

    linprocfs   /compat/linux/proc  linprocfs       rw      0       0
    linsysfs    /compat/linux/sys   linsysfs        rw      0       0
    tmpfs    /compat/linux/dev/shm  tmpfs   rw,mode=1777    0       0

As discussed with Chris, here is a patch adding how to mount the filesystem. Please tell me if there is any issue with the patch as it is my first.
