4e93a5203c Allow zero as value for certain arguments to indicate "take from disklabel". 1995-02-05 18:03:37 +00:00

55abc5794a Change the defaults for newfs to disregard the geometry in the disklabel.
We pretend we have one head with two megabyte worth of sectors per cylinder.

The code try to access another head in what it belives to the same
physical cylinder, because it belives that it would be faster than
waiting for the next free sector under this head to come around.

Most modern drives doesn't have a "classical" geometry, and thus
we end up fooling ourselves doing the above optimization.  With this
change we will fill a cylinder sequentially if we can, and thus get
much more mileage from the track-buffer/cache built into the drives.

As a result a lot of seeks to the next or previous track should be
avoided by this.

(My disk is a lot less noisy actually...)

You can still get the old behaviour, by specifying zero for the
numbers.

This will also solve the problem with newfs barfing at really big
drives.

Obtained from:	adult advice from Kirk.

3fa88dec7f Add support for filesystem-specific `-o' options, and re-implement the
most common cd9660 and nfs options like God intended them.  (It is now
possible to say

	mount -o ro,soft,bg,intr there:/foo/bar /foo/bar

again.)  This whole getmntopt() business is an incredible botch;
it never should have been anything more than a wrapper around
getsubopt(3).  Because if the way the current hackaround is implemented,
options which take arguments (like the old `rsize' and `wsize') are still
unavailable, and must be accessed the new, broken way.

(It's unimaginable how Berkeley managed to screw up one of the few things
about NFS that Sun actually got right to begin with!)

a3189e21e6 Restrict fs_maxfilesize to 2^40; this is part of a bug fix from Kirk
McKusick to work around problems in FFS related to the blkno of a 64bit
offset not fitting into an int.

3270fb5ece Put back the `:' in the trinary ?: so this can actually compile again! :) 1994-10-13 08:46:44 +00:00

72ab19aeb7 Added '-F file' option of mount_mfs. This allows me to make floppy images
without waiting for my floppy-drive all the time :-)  Might have other
interesting uses too.

3156bbb2d1 Backed out part of the last change that prevents the rpos table from
being output if <= 1 rpos; there is a bug in the kernel which doesn't
quite get along with this. Changed default #rpos to 1, and fixed up
manual page. Converted nrpos to 1 if user specifies 0.

7ce005d7c1 1) If nrpos <= 1, don't output rpos table (and set fs_cpc to 0) - disabling
the use of the rotational position table.
2) Allow specification of 0 rotational positions (disables function).
3) Make rotdelay=0 and nrpos=0 by default.

   The purpose of the above is to optimize for modern SCSI (and IDE) drives
that do read-ahead/write-behind.

404c1a5fc1 Convert to our man installation style. Also fixed long-standing bug
in `fastboot'/`fasthalt' in which the interpreter would hang around
after `reboot' or `halt' is run, causing an irritating ``Killed'' message.
