can deal with from 1GB to 2GB. I have no way to test with >1GB because I
don't have high enough density memory to get any one box over 1GB. However, I
have tested it on xp1000 & ds10 with < 1GB of memory & have verified that it
does no harm.
filesystem is discovered. Preference is given to using the kernel
environment variable vfs.root.mountfrom, which is set by the loader
according to the contents of /etc/fstab. Changes in the MD code
provide fallback mechanisms for systems not using the loader.
A more robust fallback path is also provided, with the last recourse
being to prompt on the console for a root device.
These changes drastically simplify the machine-dependant parts of
the root configuration process. In addition, support for CDROM root
devices has been removed; it was a nasty hack and didn't work.
Mike says the whole idea of a current device was a bad idea in first place,
and will be doing away with currdev.
Anyway, people are not supposed to even notice this. :-)
be ignored by default by the df(1) program. This is used mostly to
avoid stat()-ing entries that do not represent "real" disk mount
points (such as those made by an automounter such as amd.) It is
also useful not to have to stat() these entries because it takes
longer to report them that for other file systems, being that these
mount points are served by a user-level file server and resulting in
several context switches. Worse, if the automounter is down
unexpectedly, a causal df(1) will hang in an interruptible way.

only two conflicts, cdev #98 and cdev #99. These should be fixed.
MAKEDEV should probably be merged as well.
Static majors are (hopefully) going away one day soon.
This file is informational and not machine parsed by anything any more.
to config(8) for static device tables that have not existed for quite
some time. They have been aliases for 'device' for a while, and "tape"
went away entirely as it wasn't used anywhere (except in an example
in LINT.. "fixed").
