file permissions don't work when running as 'root'

**user222** · 01-03-2005

I just removed the 'write' permission for owner, group and others, but I still can write to the file if I'm logged in as 'root'. This makes it impossible to prevent accidental overwriting of a file when logged in as 'root'.

That is correct that is one of the reasons you should not be logged in as root and do maintenance task throught the use of

Code:

su -

and

Code:

sudo

Haha! They were talking about that issue on another board. I stick to staying off of root except when totally necessary for fear of phucking something up.

But why shouldn't it work? The Windows NT/XP ACL's work even when running as Administrator, so it is possible to prevent accdental overwriting of a file. Logging in as a super user should not bypass file permissions, but has the right to change it. I hope this bug would be fixed in future Linux kernel releases.

It will never be fixed as it is not a bug. *nixes have always worked this way and most likely always will.

So a bug is when the OS gives complete control to the system administrator without idiot-box warnings? Linux is many things, but idiot proof it is not. And with luck, it will never be, at least until the release of Windows Lx.

I second this... Isnt idiot proof...
you should NEVER be loged in as root,
second, root is an admin, and AS to be able to do whatever he wants.
when working with certain file, either change the file permission your working on temporaly to make your user make the mods, or issue an su command, and then change from terminal

If this strange bug exists in all the *NIX'es, then all the *NIX'es should get it fixed. It's a very big problem, especially when running Linux in single-user mode.

I like to run Linux in single-user mode, so it's a big problem. (I didn't even create a normal, non-root user account.)

we'll mate... first its not a bug, a user should not have any rights, this is windows world and it will NEVER be applied to linux or unix, it's the way it's build. If you like to have trojan, viruses and other crap doing whatever they want when logued in root, thats your choice, but to not complain that this is a bug, it is the way its built and we all like it for that.

you better stay with windows if unsafe environment is what your looking for
