[Bug-cpio] cpio pass mode fails - ubuntu linux 10.04

[Ralph P. Sobek]

Hello folks,

    I am copying files from a DVD to a disk structure.  I do NOT tell 
cpio to create directories (-d) since all are supposed to exist!  This 
concerns version : cpio (GNU cpio) 2.10.

    I make sure that the receiving directories are all user writable 
(+w)!  Nevertheless, as cpio copies from DVD to disk, it passes the 
restrictive read-only disk directory to the disk directory which thus 
becomes NON user writable and therefore the files all get an error 
message whether they are new or not.

<on DVD directory>

find save2  ! -size 0 -print | cpio -pmv /home/foobar

If I add option -0 (zero) to cpio there are fewer messages but no files 
copied!

Possibly, if the directories are to be copied, then the restrictive 
right should only be added after the directory in question has been filled!

Also, it does NOT copy files that have SPACEs in their names  whether 
(-0) null termination is used or not!  Even the insertion of antislashes 
between find and cpio has no effect:

 find save2/music ! -size 0 -print | sed 's/ /\\ /g' | cpio -pdm0 
/home/foobar

Sincerely,
