Re: HEADS UP - DEVFS ON MASTER
Just a short *WARNING*: do *NOT* activate the loading of any sound modules in loader.conf: it'll cause a panic, probably due to a bug in the kernel linker. Cheers, Alex Hornung 2009/8/4 Matthew Dillon dil...@apollo.backplane.com: Alex's GSOC project, DEVFS is now on master and active. Some care must be taken when upgrading. * A full buildworld, buildkernel, installkernel, installworld sequence is needed. No changes to fstab are needed, /dev will be mounted from devfs automatically by the kernel. * If you run a new kernel with an old world (without devfs) you will not be able to login as root, but you will still be able to login as a user and su, and you should still be able to boot single-user. In otherwords, things will be messed up but in a fixable way, until both the world and the kernel are in sync. * A great deal of testing of basic functions has been done, but there is still a very good chance of breakage. Please test and report any issues. Very few GUI components have been tested, so if X or sound stops working it may be a day or two before we can get it whacked back into shape. * The master branch may be unstable for a week as wider testing is done. * PEOPLE RUNNING CHROOTS: Character and block devices in the filesystem NO LONGER WORK. If you have chrooted or jailed areas with their own /dev, you have to use mount_devfs in those areas. Many features are now working. We have auto-cloning support for numerous devices but only a few userland utilities have been adjusted to use it. To reduce issues DEVFS will pre-create a bunch of units for numerous devices so the non-cloning userland utilities still work. In addition, fully automatic slice and partition probing and reprobing is now operational. When you fdisk a drive the slices will pop up in /dev, and when you disklabel a slice the partitinos will pop up as well. MBR and disklabel edits will properly and automatically reprobe the drive. IMHO this is a very, very cool feature. The nrelease build still has a few issues. It will work and the intaller will come up, but the installer may have trouble seeing newly created partitions (a 'retry' usually solves the problem). This is a known issue and will be fixed. -Matt Matthew Dillon dil...@backplane.com

Also /dev/pci0 was changed back to /dev/pci fixing an issue X had with devfs. -Matt
