Subject: owner,group and mode options are only applied to the deepest directory
Date: Fri, 22 Jan 2016 12:42:05 +0100

Package: coreutils
Version: 8.21

When 'install' creates nested directories the options for owner,group and mode
are only applied to the deepest directory.

Example, when I run as root :

install -o "www-data" -g "models" --mode=2775 -d /tmp/00/00/00/00

ls -la /tmp/00/00/00/00
drwxrwsr-x 2 www-data models 4096 Jan 21 16:38 .
drwxr-xr-x 3 root     root   4096 Jan 21 16:38 ..

This shows that /tmp/00/00/00/ is owned by root:root and has 755 as permissions.
The same holds for the just created /tmp/00/00/ and /tmp/00/ .
Only /tmp/00/00/00/00/ is correct.

All created directories should get the given owner,group and mode options.

System: Ubuntu 12.04.5 LTS
GNU coreutils 8.21 (deb 8.21-1ubuntu5.3 amd64)

Thanks for the report, but this is documented.  Per 'info install':

   • If the ‘--directory’ (‘-d’) option is given, ‘install’ creates each
     DIRECTORY and any missing parent directories.  Parent directories
     are created with mode ‘u=rwx,go=rx’ (755), regardless of the ‘-m’
     option or the current umask.  *Note Directory Setuid and Setgid::,
     for how the set-user-ID and set-group-ID bits of parent directories
     are inherited.

If you want to create parent directories with specific permissions, you
have to do multiple invocations.

As such, I'm closing this as not a bug, but feel free to add further
comments to this thread.
