I'll tweak a mounting point with the delay trick, as well. -- Michael --kzyvXpghYPNpLzXu Content-Type: application/pgp-signature; name=signature.asc -----BEGIN PGP SIGNATURE----- iQIzBAEBCgAdFiEEG72nH6vTowiyblFKnvQgOdbyQH0FAmmx35QACgkQnvQgOdby QH3e7A/+LneIo5ljbbB7D/MvMICz/q1BbRiZ0OeidklYIo4/VJXbVc8F2bIbhGHB JOROZvPUDz5/JUnXd/L0PmjYYF1B2LQ9Nqs1q8AO+nyHSjq/TslcRjKaiEcpO0Oz DnaXhyi5yG8b3TDUh98dOgg0ymcBbfjmCMqH7pmNfVrh5vjUv7wzg14eQ0kLrvFP l3z8HylWeFIiE1nC2fkXiXfkaJv8TUvEtKXGCDlpRz4EieY3AHF0pwFvQUNY2GCC jh08If/hnmRYjh5kGhw9NhCwTcyOqY5L7QyxXDVbAQB3Z4JY9JHY8IIrZhSWsMeK WO77h24ixaptsXa/wTayk++YCNOov87x5aTNq9gS5k6tnw6bQRB0RF2CI8gwfvbg mGlecuBYjvtuPkEyvGC4yJHFP6o7cc7fKJjfAK/DbP94OPaGo+tcp86zrXkn/LvO X5irEIqJ9yKAEfpdOHT3SogkJljZ4BdWblOEFJPYcqKgiSfWwkFs89RbKOKf9nWG 6z0Wj9/xKJUPSN5qfq9u4D3V66OWrK8rXyIjTZiiZEF3bprQgMOiPELgmYFZVD5s PwXxfaZABhtjbLGeL91vm42QOyagxhdvnJkWuIxIv3M0X+VfCpefK2Sn1ZrfiNwQ 3jK00xGnflRd0BuNSx/xYYy7M1tQ8bekYhDUd7QJZ5NuWUW3NtU= =Eln1 -----END PGP SIGNATURE----- --kzyvXpghYPNpLzXu--
