FACL, lost in it's behavior..

Hi,

I got FileA that have 640a getfacl FileA give me


<span style="color:#323232;"># file: FileA
</span><span style="color:#323232;"># owner: me
</span><span style="color:#323232;"># group: me
</span><span style="color:#323232;">user::rw-
</span><span style="color:#323232;">user:aUser:r--
</span><span style="color:#323232;">group::r-x			#effective:r--
</span><span style="color:#323232;">mask::r--
</span><span style="color:#323232;">other::---
</span>

So it’s give me the expected…

but when I do


<span style="color:#323232;">chmod 600 aFile
</span><span style="color:#323232;">getfacl aFile
</span>


<span style="color:#323232;">...
</span><span style="color:#323232;">user:aUser:r--		#effective:---
</span><span style="color:#323232;">...
</span><span style="color:#323232;">mask::---
</span><span style="color:#323232;">...
</span>

Why suddenly aUser lost his ability to read the file !?!?!

ACLs on Linux can be a bit weird. If I remember correctly, the ACL mask corresponds to the group bit when using masks. Some more details here:

<span style="color:#323232;">setfacl -m m:r aFile
</span><span style="font-style:italic;color:#969896;">#re set the mask
</span>

solve the problem, but the question is: why the F**** this is happening !?
