"It's a feature, not a bug." :-)

If you have lots of disk space, you can try using CVSup to mirror the CVS repository
and let CVS merge your changes:

* Omit the `tag' in your cvsupfile. Just don't put one in.
* Change the `prefix' to a place where you have a lot of space, such
  as /usr/local/portcvs. (Do NOT use /usr!)
* Cvsup as normal.
* You should find a lot of files in /usr/local/portcvs/ports/* with
  names ending in ",v". These are the CVS files.
* Back up your ports tree (mv /usr/ports /usr/ports.old).
* cd /usr && cvs -d /usr/local/portcvs checkout ports
* If all went well, you have a ports tree.

Now, always cvsup this way. To update your main ports tree, do
`cd /usr/ports && cvs -d /usr/local/portcvs update'. This will
try and merge your changes.

This may have been a bit difficult to understand. I'm sure someone else can
explain it better than I :-)

Hard way (tested):

#!/usr/bin/env perl

use File::Find;

find sub {
-f $_ or return;
my $file = $_;
my $filebak = "${file}~";
rename $file, $filebak or die "Can't rename $file to $filebak: $!\n";
open FILEBAK, $filebak or die "Can't open $filebak: $!\n";
open FILE, ">$file" or die "Can't write to $file: $!\n";
while () {

# Replace OLD with the "search for" -- a regexp
# Replace NEW with the "replace with"
s/OLD/NEW/g;

print FILE $_;
}
}, ".";

# end replace.pl

Easy way (not tested):

find . -type f | perl -pi~ -e 's/OLD/NEW/g;'

Maybe. Either you get to do it the hard way, or you get to use beta
software for it :-)

I think Mondo  might do the job
here. Yeah, I'm biased (I ported the thing to BSD :-), but it
seriously might work.  Note that the FreeBSD port is beta, and the
links on the downloads page for it are BROKEN. [*don't use them --
use CVS*]

Install system to one HD. Make sure you have the ports collection,
CVS, and the devtools. Install these ports:
+ devel/gmake
+ devel/newt
+ lang/perl
+ shells/bash
+ sysutils/afio
+ sysutils/cdrtools

$ export CVSROOT=:pserver:[EMAIL PROTECTED]:/mondorescue
$ cvs login
Password: 
$ cvs checkout mindi-fbsd
[snip]
$ cvs checkout mondo-devel
[snip]
$ unset CVSROOT

$ su
Password:
# cd mindi-fbsd && bash install.sh && cd ..
# cd mondo-fbsd && ./configure && make && make install && cd ..
# mondoarchive && : follow prompts && reboot && : insert CD && : interactive mode
[yes, you CAN type that command :-]

If it asks you whether to backup the MBR raw, say yes.

Make sure you set up some Vinum partitions in the mountlist
editor. Add some partitions type + mountpoint "raid", put in
/dev/vinum/something as the device (replace "something" with the
volume name you want, of course), press OK, edit that entry, select
mountpoint, press RAID.., follow prompts. Delete all non-RAID
partitions, except maybe a /boot partition or /.

Note that the RAID editor is a bit suboptimal (only uses one subdisk
per partition). Still, it works. 

Do you want to partition your disks? Yes.
Do you want to format your disks? Yes.
Do you want to restore everything? Yes.

If it doesn't work, and you feel like it, email me the problem, along
with /var/log/mondo-archive.log.

Your securelevel is set higher than 0. Please reboot into single-user mode for the

You won't be able to use IPv6. Unless you know what this is,
you don't need it.

(If you do know what it is, and you want a /64, one good site
is ipv6.he.net).

Try setting both "vol" and "pcm" to 100:100 using the mixer(8) utility.
For me at least, my soundcard is *extremely* soft unless I use 100%
volume. Sample commands:

Telnet uses port 23.
SSH uses port 22.
The protocols are not compatible -- that's why they use different ports.
Get PuTTY -- it's a great Windows SSH client. (Google for PuTTY -- it's

Yes, ignore it. The error comes from the fact that users are not allowed
to chmod in FreeBSD. Therefore root will not get this. Linux fails
silently (same problem, no error). The error causes no harm. (If it was
fatal, configure would say so). Compile away :-)

I have the Sony DRU500a drive (internal IDE version).  It works well:
$ mkisofs -r -o dvd.iso /some/large/tree/no/bigger/than/4.4g
[snip]
## You might not need to do the next command more than once
## per DVD. Substitute dvd-rw for dvd+rw if you're using that.
$ burncd -F -f /dev/acd0 format dvd+rw
$ burncd -f /dev/acd0 dvdrw dvd.iso
You might need to be root for those burncd commands; I'm not sure.
I think there's a cdrecord look-alike called dvdrecord, but I have no
experience with it. I'm not sure what the commands look like if you're
using DVD-R or DVD+R, but I assume something like `burncd -f /dev/acd0
data dvd.iso fixate' would work.

DVD+RW and DVD-RW work great for backups. For example, `dump 0uf
/path/with/big/space/dump_of_root.dump /' and burn it like an ISO. To
restore, `cd / && restore rf /dev/acd0' -- man restore for details.

I also had good experience just making an ISO of a directory (/usr/local
for example). To fit more than one of these on a DVD, you can do `mkisofs
-graft-points etc=etc var=var usr/local=usr_local usr/home=home' from the
root directory (this example makes an ISO of /etc, /var, /usr/local, and
/home and puts each one in a separate directory on the ISO.) Then `burncd
... dvdrw backup.iso'.

Here's a good backup command to get you started:
# cd / &&
> mkisofs -graft-points usr/local=usr-local usr/home=usr-home \
> var=var etc=etc -o usr/backup/DVD.current.iso &&
> burncd -F -f /dev/acd0 format dvd+rw &&
> burncd -s max -f /dev/acd0 usr/backup/DVD.current.iso &&
> mv usr/backup/DVD.current.iso \
> usr/backup/DVD.`date +%m-%d-%y`.iso &&
> echo "*** Backup Done! ***"
This assumes that you have a DVD+RW in the drive, that the drive is
/dev/acd0, and that you want to back up /usr/local, /usr/home, /var, and
/etc. Depending on your setup, this may not all fit on one DVD.
As always, YMMV.

I would get the IDE one: that's the only one I have experience with. I
don't know about SCSI. 5.0-release has the capability right out of the
box. (Note that with IDE you can emulate SCSI, if you have a program that
wants it.)

/usr/ports/sysutils/mkisofs is the only port you'll need.
