Hi VServer Experts,
I have a question about iunlink attributes.
Problem description:
-----------------------
The issue I'm facing right now is that setting attributes using
"setattr --iunlink <link>" does not survive a unmount/mount operation.
I'd like to know if the attributes IU are stored in the file system
or in the memory somehow.
Setup:
------
I use vserver version 2.0.1 with vserver-util 0.30.210 - I'm limited
to this patch by my project's kernel version :(
I use reiserfs.
More background info:
----------------------
I use the pre-COW links vserver image and vserver-utils. I'm using
setattr to actually restrict some files from the vserver instances to
prevent application in the vserver to modify those files (link targets).
What I'm currently seeing is that when I use "setattr -iunlink
<link> on a link (inside the vserver), I can see it take effect with
showattr (so good so far), but those attribute go away when I unmount
the partition and remount it. (I tried without rebooting and I'm sure
this is the cause of the attribute lost)
I assumed that the setattr flags for iunlink (UI) where set in the
file system and were non-volatile (survive a unmount/mount operation).
Is this the expected behavior?
Is there a workaround or documentation that could help me out with this?
Thanx for your time.
/Éric
