It's not a bug, it's a feature ;) You are running a late 2.1-series kernel,
which introduced the lchown(2) call. It used to be that chown(2) changed
the owner of the link, now it changes the owner of whatever the link points
to (and fails with ENOENT if it's a dangling symlink). Compile this snippet
with "cc -fPIC -Wl,-shared -o chown.so chown.c" and set LD_PRELOAD to point
to the resulting .so before running dpkg:
--->8---
#define __LIBRARY__
#include <asm/unistd.h>
/* Quick wrapper to turn chown into lchown */
#ifndef __NR_lchown
#define __NR_lchown 208
#endif
_syscall3(int, lchown, const char *, path, int, owner, int, group);
int chown(const char *path, int owner, int group)
{
return lchown(path,owner,group);
}
