Hi,
I just noticed that Mark Shellenbaum has replied to the same question in
a thread "ACL not being inherited correctly" on zfs-discuss.
Sorry for the noise.
Out of curiosity, I would still be interested in answers to this question:
It there a reason why inheritable ACEs are split always, even if the
particular chmod call would not require splitting them?
For instance, a mode bit change would never influence
n...@owner/@group/@everyone ACEs and even for the
@owner/@group/@everyone, one could check if the mode bits are actually
changed by the chmod call.
Any group entry could have its permissions modified in some situations
(i.e. group has greater permissions than owner). Its true that a user
entry wouldn't necessarily need it, but in order to keep the algorithm
simpler we just always do the split.
It would be simple enough to exclude user entries from splitting. Feel
free to open a bug on this.
Does this make any sense?
Thank you,
Nils
