setting default directory ACLs using xargs

[Doug Sampson]

I need to do this at the command prompt for all directories:

root at aries:/data/Products# getfacl -d .
# file: .
# owner: DSP-alfredo
# group: DSP-production
root at aries:/data/Products# getfacl . | setfacl -d -b -n -M - .
root at aries:/data/Products# getfacl -d .
# file: .
# owner: DSP-alfredo
# group: DSP-production
user::rwx
user:DSP-alfredo:rwx
group::rwx
group:DSP-production:rwx
mask::rwx
other::r-x
root at aries:/data/Products# 

okay, it works.

Now, I have thousands of subdirectories that I want to apply this to. When I
attempt to use the xarg command with the above command modified to work with
xargs, I end up with an error message:

root at aries:/data/Products/RSVP# find . -type d -print0 | xargs -0 getfacl |
setfacl -d -b -n -M -
setfacl: line too long in -
root at aries:/data/Products/RSVP#

Okay, that doesn't work. What is the output of...

root at aries:/data/Products/RSVP# find . -type d -print0 | xargs -0 getfacl 
# file: .

Seems there are approximately 10 lines of output for each 'getfacl' command.
How do I feed each group of ten lines into the next command of 'setfacl'?
The manpages of xargs are a bit cryptic for me.

NOTE: There appears to be a known bug with the 'setfacl' utility when
attempting to set default ACLs on directories. See
http://lists.freebsd.org/pipermail/freebsd-fs/2005-May/001053.html for more
details. This is what led me to the workaround of:

$ getfacl /aclTest/ | setfacl -d -b -n -M - /aclTest/

which actually works for me. I do dread the idea of having to manually apply
this to all existing directories in the /data filesystem. Thousands of them.

Trying again:

root at aries:/data/Products/RSVP# find . -type d -print0 | xargs -0 getfacl .
| setfacl -d -b -n -M -
setfacl: line too long in -
root at aries:/data/Products/RSVP# find . -type d -print0 | xargs -0 getfacl .
| setfacl -d -b -n -M - .
setfacl: line too long in -
root at aries:/data/Products/RSVP# find . -type d -print0 | xargs -0 getfacl .
| xargs -0 setfacl -d -b -n -M - .
setfacl: illegal filename: Inappropriate ioctl for device
root at aries:/data/Products/RSVP# find . -type d -print0 | xargs -0 getfacl .
| setfacl -d -b -n -M - .
setfacl: line too long in -
root at aries:/data/Products/RSVP#

Any ideas?
