Sorry if you get multiple copies of this.
The test for this is failing on solaris 10 (NFS)
It does seem that hardlinks to symlinks are supported:
$ touch tfile
$ ln -s tfile tlink
$ src/ln -L tlink tlink-ln-L
$ src/ln -P tlink tlink-ln-P
$ src/ln tlink tlink-ln
$ ls -li tfile tlink*
8550 -rw-r--r-- 3 padraig csw 0 Dec 9 01:18 tfile
8551 lrwxrwxrwx 2 padraig csw 5 Dec 9 01:19 tlink -> tfile
8550 -rw-r--r-- 3 padraig csw 0 Dec 9 01:18 tlink-ln
8550 -rw-r--r-- 3 padraig csw 0 Dec 9 01:18 tlink-ln-L
8551 lrwxrwxrwx 2 padraig csw 5 Dec 9 01:19 tlink-ln-P ->
tfile
But we have linkat() emulation in place I think:
$ grep LINK lib/config.h
/* #undef CHOWN_MODIFIES_SYMLINK */
#define GNULIB_AREADLINKAT 1
#define GNULIB_TEST_LINK 1
#define GNULIB_TEST_LINKAT 1
#define GNULIB_TEST_READLINK 1
#define GNULIB_TEST_READLINKAT 1
#define GNULIB_TEST_SYMLINK 1
#define GNULIB_TEST_SYMLINKAT 1
#define GNULIB_TEST_UNLINK 1
#define GNULIB_TEST_UNLINKAT 1
#define HAVE_LINK 1
/* #undef HAVE_LINKAT */
#define HAVE_READLINK 1
/* #undef HAVE_READLINKAT */
#define HAVE_SYMLINK 1
/* #undef HAVE_SYMLINKAT */
#define HAVE_UNLINKAT 1
/* #undef LINKAT_TRAILING_SLASH_BUG */
#define LINK_FOLLOWS_SYMLINKS -1
#define LSTAT_FOLLOWS_SLASHED_SYMLINK 1
#define PIPE_LINK_COUNT_MAX (0)
/* #undef READLINK_TRAILING_SLASH_BUG */
/* #undef RENAME_HARD_LINK_BUG */
/* #undef UNLINK_CANNOT_UNLINK_DIR */
/* #undef UNLINK_PARENT_BUG */
I've attached the verbose log for the test,
as I've not time to look into it at present.
thanks,
Pádraig.
