Why not? My computer does a installworld+mergemaster in approx. 30 minutes and it is an old 166 MHz Pentium with only 32 MB RAM (and with a IDE controller that hasn't even heard of UDMA.) I would expect it to be significantly faster on a modern machine and 15 min sounds quite plausible for a modern laptop with a somewhat slow disk. -- Erik Trulsson ertr1013@student.uu.se To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
