have a simple test case:
as root (w /umask 002):
mkdir -p dir/{a,b}
touch dir/b/file
ln -s ../b/file dir/a/symfile
---
So now tree should look like:
tree -AFugp dir
dir
+-- [drwxrwxr-x root root ] a/
| +-- [lrwxrwxrwx root root ] symfile -> ../b/file
+-- [drwxrwxr-x root root ] b/
+-- [-rw-rw-r-- root root ] file
----
Now, w/normal user, who is in group root, try:
cp -al dir dir2
cp: cannot create hard link ‘dir2/dir/a/symfile’ to ‘dir/a/symfile’: Operation
not permitted
-----
Trying to link to a symlink is the bug --
it used to duplicate the symlink.
This is a recent behavior
change -- i.e. looking at earlier behavior, the symlinks,
like the directories are created as the 'user', and
only files are linked to.
Core utils version: 8.21 (suse rpm coreutils-8.21-7.7.7.x86_64)
Any idea how this managed to be broken?
