Without write access, the ctime cannot be changed.

$ su bin

$ touch a

With write access, the ctime can be set to the current time, but not to
|
|
any other time:
|
|
$ su
|
|
$ nfs4acl --set 'bin:rw::allow' a
|
|
|
|
$ su bin
|
|
$ touch a
|
|
$ [ b -ot a ] || echo 'b should be older than a'
|
|
$ touch -r b a
|
|
> touch: setting times of `a': Operation not permitted
|
|
|
|
With set_attributes access, the ctime can be set to an arbitrary time:
|
|
$ su
|
|
$ nfs4acl --set 'bin:rwt::allow' a
|
|
|
|
$ su bin
|
|
$ touch -r b a
|
|
$ [ b -ot a -o a -ot b ] && echo 'a should be as old as b'
|
|
|
|
$ su

$ cd ..
