fstab

[David]

Hullo,


Installing FreeBSD to an Optiplex 980.

On installing Gnome as a desktop, and restarting, I get a fault to the
effect that the FStype is wrong.

I'm following directions in the handbook.

What I have is:


# Device              Mountpoint FStype               Options         
Dump          Pass#

proc                     /proc procfs                  rw              
   0                   0


I can't see what's wrong.

Can anybody point to what I'm missing?

Thanks for any time and trouble.

Does mount -t procfs proc /proc work?

No, it doesn't appear to.

I'm short on time, and will have to come back to this when I have more
time, I think.

Thanking you for time and trouble.

Hello David,

Your fstab configuration looks fine and should work as expected. One possibility is that you're using a custom kernel that doesn't have PROCFS support enabled.

Could you please verify whether PROCFS is included in your kernel configuration? Additionally, try mounting the filesystem manually( mount -t procfs proc /proc) and let me know the exact error message you receive.

If you can share the exact FreeBSD version and platform (e.g., architecture or hardware model), I’ll be happy to try and reproduce the issue on my end.

If the module is supposed to be loaded dynamically then please check kldstat output as well and see required modules are loaded.

Thanks & Regards,
Rupesh Pilania

If you're not familiar with doing this, a quick way is "kldstat -v |
grep procfs". Here's one of my machines:


root@arthur:1 ▶ kldstat -v | grep procfs
351 procfs

I've no idea what the number is for, yours may be different, it's the
presence of procfs that matters.

Had you not piped the output you would see exactly what the number is for.

You can avoid the pipe entirely with '-m module' and it'll preserve the headers.
You can then read kldstat(8) for even further information on what each
field represents if you desire.

I think your device is wrong. My fstab:

#Device Mount FStype Options Dump Pass#
procfs /proc procfs rw 0 0
fdesc /dev/fd fdescfs rw 0 0
tmpfs /tmp tmpfs rw,mode=1777,noexec,nosuid 0 0

man procfs
PROCFS(5) FreeBSD File Formats Manual PROCFS(5)

NAME
procfs – process file system

SYNOPSIS

proc /proc procfs rw 0 0

DESCRIPTION
This functionality is deprecated. Users are advised to use
libprocstat(3) and kvm(3) instead.

The process file system, or procfs, implements a view of the system
process table inside the file system. It is normally mounted on /proc.


I can't find anything that uses procfs anymore.

I remember that openjdk is using procfs

No, the vanilla kernel as supplied with the 14.3 install.

Yes, I ran that.

I think it wound up being a gdm problem.
It didn't seem to want to load.
I've dropped gnome, now, and xfce is working - for the most part - I
just have to do some fine tuning.
I'm sending this with evolution on the new install.
Thanking you.

It's noted in the handbook as a prerequisite for Gnome-desktop, also.
Cheers!
