ACLs on /target/ while installation causing trouble

[steven.wend at t-online.de]

Hello members, hello Thomas,

I have a question regarding to the handling of ACLs. We have trouble with 
some applications while using the installed maschines because the complete 
filesystem has ACLs.

Actually I was wondering about this behavior, because a plain installation 
of Ubuntu 16.04 without FAI doesn't set ACLs. So I started reading the fai 
code and found the switch for tar ($catname $file | tar --xattrs 
--xattrs-include=*.* --selinux --acl --numeric-owner -C /tmp/aclmist -v -xf 
-) inside the ftar.

After that I tried to figure out which ACL rule could be used by tar and I 
recognized that the target directory (while installation) has set ACLs.

boot/vmlinuz-3.16.0-4-amd64

Is this the expected behavior for fai? Or did I miss a switch to deactivate 
the ACL for /target/ ?
 
Other switches for ACLs weren't found by me.
 

Thanks for your help and have a good evening,

Steven
