Solved man hier

[fernandel]

Hi!

Today I ran man hier and I found that I have Symlink ~sys (/usr/src/sys).
Is it "normal". I do not remember that I did it.
It was when I installed FreeBSD 13.0_RELEASE on my new laptop Thinkpad T495. It was 2021.
Thank you.

i always had a /sys -> /usr/src/sys

Is it "normal". I do not remember that I did it.

It's created when you installed FreeBSD. Yes, it's perfectly normal. It's been there for as long as I can remember (FreeBSD 3.0, probably even before that).

# ll -d /sys
lrwxr-xr-x  1 root wheel 11 May  4  2024 /sys@ -> usr/src/sys

/sys as symlink has been used at least since 1982 (pre 4.2BSD)! Not sure /sys is particularly useful any more.

The problem is I never read a hier and I am using FreeBSD from version 6?. Uh...
Thank you.

I do not know if it is always present. It should be created only if you install sources during installation.

I've never installed sources, and it is there.

On the other hand, I do wonder why it still exists. Is it useful? Do scripts still use /sys instead usr /usr/src/sys?
