The problem with such home brewed systems is that they may start simple but you keep adding more conditions, like these, making them anything but simple. Now you're considering rebooting just to make an update, even Windows doesn't need that (well, not all the time). Alan's point about network connectivity is also important. What happens if you unplug your laptop and leave the office while someone is mid-sync? With emerge -b, the package is downloaded before anything is installed, so losing contact with the package host would be less critical. It could still cause problems if it happened while updating some inter-dependent packages, which is why I would prefer to use a static package repository. --=20 Neil Bothwick If Yoda so strong in force is, why words in right order he cannot put? --Sig_/S3+LxUqNQSNvu8uViUgY8V2 Content-Type: application/pgp-signature; name=signature.asc Content-Disposition: attachment; filename=signature.asc -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.22 (GNU/Linux) iEYEARECAAYFAlKq0PMACgkQum4al0N1GQM/agCfQcuFYH0ixagAuAGHfW1HexeX lr0AoMN59NcHdxjvTCzwfuoKNCu4OEhy =O24b -----END PGP SIGNATURE----- --Sig_/S3+LxUqNQSNvu8uViUgY8V2--
