This could be considered one part of bug #28891.

For now, I've written a simple, hacky patch (attached) that makes "mkdir -p" unconditionally observe default ACLs for ancestor directories but does not change the behavior for the actual argument directory.  This should be enough for "mkdir -p -m 755" to give usable permissions when installing software.  Others might wish to use this patch until a complete solution is available.

(file #19699)

I don't take that text in the standard literally.  In the hypothetical "POSIX plus abandoned POSIX ACLs" standard that we're implementing, I feel certain it would have been changed to account for default ACLs.

I really doubt that a user who applies a default ACL to a directory would then rely on mkdir honoring the umask in preference to the default ACL.  But if you're genuinely worried about breakage, I would be happy to have a new option, or preferably a new environment variable that I could set globally.  This issue causes me pain every time I install software from source: since I use umask 0077, installs into a shared directory with an appropriate default ACL are unusable by others until I go and change the permissions manually.

Sorry, but POSIX requires that "mkdir -p FOO/BAR" must create FOO as if by the following command:

mkdir -m $(umask -S),u+wx FOO

See:

http://www.opengroup.org/susv3/utilities/mkdir.html

It might make sense to add the behavior you desire, as a new option to mkdir, but I'd have some qualms about changing the existing, standard behavior, as people may be relying on it.

I would like mkdir -p to observe the default ACL in preference to the umask (as nearly all other programs do) when creating parent directories.

To reproduce, run this in an empty directory on a filesystem with ACLs enabled:
umask 0077
setfacl -dm u::rwx,g::rwx,o::rwx .
mkdir foo
mkdir -p bar/baz
ls -l

Actual result:
total 0
drwx------+ 3 matt matt 72 Apr  7 11:32 bar
drwxrwxrwx+ 2 matt matt 48 Apr  7 11:32 foo

Desired result:
total 0
drwxrwxrwx+ 3 matt matt 72 Apr  7 11:32 bar
drwxrwxrwx+ 2 matt matt 48 Apr  7 11:32 foo
