I hear there's good reasons for not > running my whole system off of a single partition. The three main reasons are: Backups. It is often easier to manage backups when the disk storage is thoughtfully divided into reasonable and functional pieces. Emergencies. If your system crashes, especially if it is due to some disk problem, you may need to boot your system to single user. In that case you will start with only / (root) mounted as read-only. Having a fairly small root partition means the chance of having the bad disk area be in what you are trying to mount is reduced (not eliminated, of course). Anyway, you may be more able to get up to a minimal system and then work on recovering the other partitions. Boot time. A possible benefit is that only root needs to be fsck-ed before other things can start. Remaining fsck-s can run in parallel. This will take you less time to get back up after an abnormal shutdown - such as from a sudden power loss. > The 'other' system > has 7.2 and has devolved to a 25% chance of a hard freeze every time I > unplug a ucom device (seems to have cropped up between 7.2-release and > 7.2-stable#3). 8 likes usb, so I like 8. FreeBSd 8 is a good choice. ////jerry > > Steve > _______________________________________________ > freebsd-questions@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-questions > To unsubscribe, send any mail to "freebsd-questions-unsubscribe@freebsd.org" >
