Hello All,

 Got a basic question regarding ACL..what will the file/directory permission
created in a ACL configured partition. Does it takes the UMASK permission or
the ACL permission.

Example:
Hello,

 Got some queries regarding ACL's, please help me.

1. I got a partition with ACL configured. Operating System is RHEL4 U-4.
]# mount -o acl /dev/sda5 /test
]# getfacl test
# file: .
# owner: root
# group: root
user::rwx
group::r-x
mask::r-x
other::r-x
]# ls -ld /test
drwxr-xr-x 3 root root 1024 Dec 28 13:59 /test
]# chown jeetu.apple /test
drwxr-xr-x 3 jeetu apple 1024 Dec 28 14:01 /test
]# cd /test
]# mkdir testroot
]# ls -ld testroot
drwxr-xr-x  2 root     root      1024 Dec 28 14:10 testroot
]# getfacl testroot
# file: testroot
# owner: root
# group: root
user::rwx
group::r-x
other::r-x
]# setfacl -m u:jisa:rwx testroot
]# getfacl testroot
# file: testroot
# owner: root
# group: root
user::rwx
user:jisa:rwx
group::r-x
mask::rwx
other::r-x
]# ls -ld testroot
drwxrwxr-x+ 2 root root 1024 Dec 28 14:52 testroot

* Why does the group permission change here? If I'm not specifying rwx for
the user jisa and only rx, then the group permission does not changes.
]# setfacl -x u:jisa testroot
]# setfacl -m u:jisa:rx testroot
]# ls -ld testroot
drwxr-xr-x+ 2 root root 1024 Dec 28 15:12 testroot
]# getfacl testroot
# file: testroot
# owner: root
# group: root
user::rwx
user:jisa:rx
group::r-x
mask::rwx
other::r-x

* Whenever I create a file/directory, how does the permission is set for the
file/directory? Does it takes the UMASK permission of the owner who's
creating the file/directory or does it sets the permission of the parent
directory or does it sets according to the ACL value of the parent
directory.

Thanks in advance,
JI
