man chmod-
[...]
RESTRICTED DELETION FLAG OR STICKY BIT
[...]
For directories, it prevents unprivileged users from removing or re_ naming a file in the directory unless they own the file or the directory;

alice@debian:/tmp$ ls -l aclfile
-rw-rw-r--+ 1 alice alice 25 Jul 6 11:53 aclfile
getfacl -c aclfile
user::rw-
user:bob:rw-
group::r--
mask::rw-
other::r--
so theorically bob should be able to write into that file (aclfile)
bob@debian:/tmp$ echo 'write from bob' >> aclfile
-bash: aclfile: Permission denied
Nore vi does allow 'write access'.
I remove sticky bit from parent dir:
root@debian:~# chmod -v o-t /tmp
mode of '/tmp' changed from 1777 (rwxrwxrwt) to 0777 (rwxrwxrwx)
root@debian:~# ls -ld /tmp
drwxrwxrwx 15 root root 4096 Jul 6 12:01 /tmp
bob@debian:/tmp$ echo 'write from bob' >> aclfile-
bob@debian:/tmp$ cat aclfile
write from bob
so my question is: Why the sticky bit on the parent dir does-
not allow a user (with write access via acl) to write into that file?
thanx folks !
