Known limitation in dash - it is going off of just st_mode bits instead of using faccessat() and honoring ACLs. My guess is that if you do 'getfacl /Users/tmcdaniel/AppData/Local/Temp' and 'id', you will find that your current uid and gid are not the owner of the directory, but do have an ACL granting write access to the directory anyway. I've been meaning to do a new build of dash (aka ash), and to force the use of faccessat as part of that build; I just haven't had the time to get to it yet. --=20 Eric Blake eblake@redhat.com +1-919-301-3266 Libvirt virtualization library http://libvirt.org --------------enig1096E1621D18D99CBA2062AA Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) Comment: Public key at http://people.redhat.com/eblake/eblake.gpg Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iQEcBAEBCAAGBQJO1rIkAAoJEKeha0olJ0NqNZkH/3mYnNNYLN337qPtAl5Mg7ki VjM8ezJH6wKNl0UwYWCH+W+Tjo+BuzrCUvqze1kaz58IyQFjM/vR1n+CFmAqN/99 wPupIm4nDeYflGdFpNZI6D5MW+vJboO7kTfB27OUIbxQcSxcOqpspWq6+6frtJj0 xwHdxMydbiB1J2Vdy++m2JC2rd4Q2frydkIZGJlsbefewms3z2EP6FJtgCWLDXcT 9BSymcBEaZGF1wFhoEgkLVMJ2Icld02CgGpjQ5PYEizUTeNb+p7XA4fJWPl3g/Bb OAkBCR5DTDxfnF3ysALw9BmdwlHi1V4oFPtqcJ5RLzatP5qJwEvLVTd7tvRTQso= =F4UH -----END PGP SIGNATURE----- --------------enig1096E1621D18D99CBA2062AA--
