>Description:
The fix in rev 1.40 (jkh) of usr.sbin/pkg_install/lib/file.c to handle sym
linked dirs doesn't catch sym links deeper than one.
>How-To-Repeat:
mkdir /tmp/prefix
ln -s /tmp/prefix /tmp/a
ln -s /tmp/a /tmp/b
pkg_add -p /tmp/b some_pkg.tgz
You should see something to the effect of:
pkg_add: extract_plist: unable to cwd to '/tmp/b'
>Fix:
Follow sym link all the way to '.'
(patch against -current version of the file...)
