>Description:
As discovered when reviewing mtree(8) as part of bin/144411, there are a number
of items with -P that doesn't work... all chown, chmod, and stat calls for
instance are the non-l variety, which means that unfortunately the file
information for symlinks isn't being properly recorded.
Furthermore, in verify.c where lchown is used:
if (!(p->flags & (F_UID | F_UNAME)))
(void)printf(" (%s not created: user not
specified)", type);
else if (!(p->flags & (F_GID | F_GNAME)))
(void)printf(" (%s not created: group not
specified)", type);
else if (p->type == F_LINK) {
if (symlink(p->slink, path))
(void)printf(" (symlink not created:
%s)\n",
strerror(errno));
else
(void)printf(" (created)\n");
if (lchown(path, p->st_uid, p->st_gid) == -1) {
the symlink data isn't being properly recorded; it's resolving the file
instead, which may store incorrect data, or may have incorrect permissions.
