Moving /home

It's not? The OP seems to have originally placed /home on the
/ partition, and now wants it on its own partition. He probably
wants to be able to erase / without disturbing /home.
 

Why?
 

If users are logged in moving /home could cause problems. The
most sure way is to go to runlevel 1, log in directly as root, and
then move /home to its final destination e.g.

mount /dev/hda88 /mnt/newhome
cd /home
tar cf - . | (cd /mnt/newhome;tar xvf -)

# (force of habit; the equivalent mv should work too)
# verify newhome is good; then
rm -rf /home
# or
mv /home /oldhome
mkdir /home
mount /dev/hda88 /home
# now edit /etc/fstab and add an entry for /home

If runlevel 1 is not an option, then set /etc/nologin or equivalent
(like beating your users over the head with a hockey stick if they
log in), kill off any processes using /home (lsof can help here), then
do the above.

You need to remove or move the old /home before mounting the new
/home if you want to be able to eventually free up that space without
having to umount the new /home. If you don't move it out of the way,
the new mount will mask the existing files, and there will be no way
to delete them without umounting the new /home.

How to set the order of init.d scripts.

On most Linux systems, the "chkconfig" command is used to read the

Take a look in /etc/rc.d/rc3.d to get a sense of what happens at
runlevel 3, and at the contents of the files and the man page for
chkconfig.

Ok, this appears to be supported by open source DRI drivers. I have not

would try and find someone who has a similar laptop, and test it with a live

I can tell, so I would avoid these at this time.

Is there an easy way to install apps on Linux

Posted: 11 May 2007 01:43 PM PDT

On 11 May 2007, in the Usenet newsgroup comp.os.linux.setup, in article
<googlegroups.com>, Roger wrote:
 

As you are new to Linux, your best bet is to use the applications that
come with your distribution (or in the case of *buntu, the applications
available through Debian), and you _REALLY_ want to be using the
package manager for this.

1: The packages have been inspected, poked at, tested AND someone
is keeping an eye on it for security problems.

2: The package manager keeps track of what is installed, where, and
what conflicts and dependencies exist, AND how to resolve them.

3. The package manager can handle updates, and the safe removal of
packages without breaking the system.

Do you know how to do all of that? Are you aware of the consequences
if you are not able to do so?

Unlike windoze, there are (literally) hundreds of different Linux
distributions, and they use several different package tools. Most often,
packages are built for a specific release of a specific distribution,
much as a fender for a 2006 Plymouth PT Cruiser isn't going to fit very
well on a 2004 Chevrolet Corvette. or a 1957 Ford Thunderbird. The
common tool among all distributions is the tar file and compiling from
source - which is still simpler than you trying to figure out how to
bash that piece of sheet metal (or fiberglass) into something that may
be made to fit and function like a fender.
 

Then why are you using a keyboard? Can't you just click on some icon
and have your thoughts translated directly to words in some web-form?
 

uhuh
 

The reason it did not is because that cryptic command stuff can do things
that your GUI can't do because the author never thought you'd need or
want to do so. If the GUI author didn't include it, you can't do it.
Amazing. Additionally, the commands can be chained together to do
things quite different, and rapidly without much effort. In reality,
while there are a lot of "cryptic" commands on the computer, you rarely
use even ten percent of them. Here, there are over 1300 commands in my
PATH as a user - yet I average using around 80 commands to accomplish
everything I use the computer for. Tell me where the icons are that you
can use to find out how many commands are on your system, and which ones
you are using.

Active mode FTP over PPP

Mark Hobley <deletethisbit.com> wrote:
 

The three servers are connected to each other by ethernet. I have an idea.

Keep all the servers on 192.168.0.*

On the modem panels provide DHCP addresses as: 192.168.1.* for the first panel
through to 192.168.254.* and use a subnet mask of 255.255.255.0.

This allows 254 modem panels, each containing 254 modems. (Presumably you
don't have any more than this.)

(Remember you cannot use *.0 and *.255 for client addresses)

A dialling in client then requests its PPP address via DHCP, and is placed on
the 192.168.1.* network (presuming the first panel takes the call)

You still need to activate packet forwarding on server A, but this is trivial.

I assume here that all 64516 modems are connected to server A, obviously you
need to adjust this model to suit your layout.

Mark.

<KiT%h.1834$%phx>: 

Well, really, everyone knows that the normal method of designating
partitions with single letters starting with C:, D:, etc. is just so
intuitive! :-)

I'll admit I'm of two minds of all this. The HP mindset -- since HP
originally had a nomenclature that identified a drive by SCSI ID --
is a bit brittle; what if one changes the scsi ID? A similar problem
exists for the Linux ordering, which is basically first drive /dev/sda,
second drive /dev/sdb, etc., regardless of whether drive #1 is id 0, id
1, id 3, etc.

However, there's a third alternative...and in fact, several more.
Take a look at /dev/disk; one will find three alternate choices
to the standard /dev/hda1 nomenclature.

/dev/disk/by-id:
Entries here are symlinks, with names starting with the interface type
(ata or scsi, presumably), followed by an identifier read from the drive
(I have a Maxtor_98196H8_V80BT60C and a
WDC_WD800LB-55DNA0_WD-WMADW1096956, apparently; it's possible that
there's a unique identifier in there somewhere as a lot of systems are
configured with two identical model drives), followed by -partNN if it's
a partition as opposed to the entire drive.

/dev/disk/by-path:
Entries here are also symlinks. I'm not entirely sure what the first
part is on other systems (on mine it's pci-0000:00:02.5, which is
probably an indication of where the interface card, or in my case
which onboard controller, is), followed by 0 or 1, followed by colon,
followed by 0 (master) or 1 (slave), followed by -partNN as before.

/dev/disk/by-uuid:
Entries here are symlinks, and apparently represent a UUID generated
when the partition was formatted for use.

This is all part of udev. Presumably mount doesn't care whether it's
accessing the device directly (/dev/hda1) or a symlink that's correctly
pointing to the device.

Of course, during booting, all of this isn't quite set up
yet, so there's not a lot one can do; I happen to like GRUB
but LILO might make more sense for those already familiar
with e.g. /dev/hda1.

Thanks, guys, for the feedback.

Now I know that at least I'm not alone with erratic CD-ROM behavior. I did
give the the thing a cleaning, which helped some. I'll get another one if I
must.

BTW, the problems were from CD-R discs for the most part, though some may
have actually been industrially-pressed CDs. I have no expectation of any
results from any DVD or CD-RW disc.

Duplicate Linux Disk

On Wed, 02 May 2007 23:29:35 -0700, com wrote:
 
If you are using the grub loader, then you will need to install grub on
the second disk. This is because you used tar to copy the partition, which
is the correct way to do it, IMO, BTW. It is correct way to copy because
it allows for the source partition to have different properties than the
destination partition (size, filesystem, etc.) You just have to remember
to account for the bootloader.

The final fixups for making sure the copy will work as intended. Two
of the fixups are as follows:
(1) grub needs to be installed, and its menu verified,
and
(2) /etc/fstab needs to be edited (that is, if you intend to boot
without recabling.) The FC distribution may use "disk lables"
instead of standard device names which is a big annoyance for me.
If you are going to recable in the event of a drive failure, then you may
not need to do this step.
