DragonFly BSD 2.4

2.4.0 is a bigger release than normal. The single most invasive change is the introduction of DEVFS. The /dev filesystem is now mounted by the kernel after it mounts the root filesystem. All major and minor numbers have changed and the old /dev is no longer meaningful. People who use jails or chroots will need to adjust their scripts to either mount_null /dev into their jails and chroots or to make independent DEVFS mounts via mount_devfs into their jails and chroots.

Within DEVFS the entire tty/pty scheme has changed. Users upgrading from 2.2 need to be absolutely sure to upgrade their world and kernel at the same time or fireworks may ensue.

With this release the libc major number has also been bumped from 6 to 7. Applications should remain fairly compatible across the upgrade but we recommend that all applications be recompiled and/or fresh binary packages be loaded from pkgsrc.

With this release our new native AHCI driver is now standard. If your system is AHCI-capable and AHCI-enabled the new driver will take over from NATA and drives may wind up being renamed due to this. For example, ad6 might become da0. Any legacy ATA ports will continue to be probed by the NATA driver but their drives may be named differently. USB mass storage devices will also be numbered starting at 8, for example da8, to avoid conflicting with lower-numbered da* devices.
