Bug ID: 191974
Summary: |ln -sF| never calls rmdir(2) on target_file ==
target_dir, only target_dir/basename
Product: Base System
Version: 11.0-CURRENT
Hardware: Any
OS: Any
Status: Needs Triage
Severity: Affects Only Me
Priority: ---
Component: bin
Assignee: freebsd-bugs@FreeBSD.org
Reporter: jbe...@vfemail.net
Blocks: 92149
According to the manpage -F option is supposed to make ln(1) remove
target_file which happens to be a directory. What actually happens is
target_file converted to target_dir/basename and always fails when tested
with S_ISDIR().
It's also unclear why -s flag is required. If the source_file is not
a directory ln(1) can just call rmdir(2) + link(2) instead of rmdir(2) +
symlink(2).
$ echo >foo
$ mkdir bar
$ ln -sF foo bar
$ ls bar
foo
but replacing children works fine
$ echo >foo
$ mkdir -p bar/foo
$ ln -sF foo bar
$ stat -x bar/foo | head -2
File: "bar/foo"
Size: 3 FileType: Symbolic Link
