I agree that more partitions make things slightly more difficult. For me
the reason to have a separate /home is that for a beginning user there
may be times when you made such a mess that you want to do a fresh
install, or times when you would like to try a new or different
distribution. At that point in time a separate partition will allow you
to keep all personal files, which are on the /home partition and even
some usefull system files (fi the /etc/ directory) which are copied to
that partition, while you format the root / partition. I find it rather
tedious to restore my personal files (300 MB) from the back-ups, never
mind losing all my mp3's.

The benefit of more partitions is IMHO only relevant for systems in a
more professional setting, not really in a home situation.

It's true there is tradeoff and the home user may want something
simple above all, but I find I need a minimum of 4 partitions.
/home is its own partition because it remains stable over many many OS
upgraded.
I use a swap partition because that is more efficient than swapfiles.
Then in the simplest case I will still want two / partitions. The one
that I currently rely on, and the one where I will install the next OS
(or if I just installed, the new one plus the old one as a safety net
in case the new install hits problems). Sometimes I have three /
partitions if I'm doing a lot of experimenting. I feel much freer to
try stuff out in an install if I know for a fact that the old system
is just a reboot away. Of course this means keeping either a bit of
wasted disk space at all times, and/or keeping / down to a reasonable
size. These days I put big stuff that's not terribly vital (MP3s from
my CDs, games I buy, raw scans from my scanners) on separate
partitions too. In an emergency I have spare disk space just a few
simple commands away.
Cheers,
Chris

You said that you needed to update to kernel 2.2.18 to get your Epson 636U
scanner working smoothly. Would you elaborate, please? I'm asking because
I've just ordered a rebuilt 610U, and I want to be prepared for it when it
arrives. My Mandrake 7.2 distribution came with a heavily patched 2.2.17
kernel, and it appears that it'll support the USB scanner. /proc/bus/usb/
seems to have valid USB port information, and the 'usbcore.o' and
'scanner.o' modules came pre-compiled with the distribution. Is there
something that you recommend I watch out for?
Thanks.

Never had a sudden power failure that caused one of your filesystems to
get completely scribbled? (NOTE: The first time I typed this sentence,
about an hour ago, the power went out 15 seconds later and stayed out
for 45 minutes. No data loss; I was lucky.) The main benefit to having
multiple partitions here is that filesystem damage will most likely
affect only one. Let's say you have /usr, /, and /home. If your /usr
is mangled, your data and basic utilities are still there. If /home is
mangled, you still have a working system you can use to restore your
data from backups. If / is mangled, at least you don't have to spend
time recovering your apps and data, just the stuff in /bin /etc /dev
/sbin /var.
Now if you just have /, and it gets toasted, everything's gone. Eggs.
Basket. You know.

One partition is more flexible, but less safe. One partition also
limits you in some ways--my system used to run two distros, and each
shared /home and /usr/local, cutting down drastically on disk space
requirements. I would say that if you want maximum flex, the best way
to go is this: One 20M ext2 /boot, one 128M swap, one (large) ReiserFS
/ , regular backups. (You don't want one huge ReiserFS / as you'd have
to mount it with --notail or the bootloader would get confused. Having
tails is one of ReiserFS's advantages...)

Having /home on a separate partition is handy when you screw
something up in the system and want to restore from a backup
without blowing away any of your user's home directories. If
you're the only person who uses the machine I suppose it isn't
such a big deal, but when several people have to use it and
expect to find things the way they left them they don't
appreciate finding that all their work since the last backup got
blown away because you were screwing around trying to update
glibc or something. If you spool mail for users you may also
want /var on a separate partition for the same reason (Huh?! How
come I don't have any email? I know I emailed myself that Really
Important Document so I could keep working on it here! If it's
that $%#$@-ing [insert name here] farting around with "improving"

This doesn't make sense. Bttv doesn't have this program and it doesn't come as
an RPM (even if it does it would be nearly useless because you'd have to patch
the kernel and compile anyway). I recommend you use the driver provided with the
kernel.

The program you were trying isn't really fit for the task (I don't think anyone
is using it these days). Start with xawtv, which works quite well (although the
interface leaves a lot to be desired). Zapping is an alternative, although I
believe it needs Linux 2.4 for best performance.

Since SysV R3 (with symbolic links) it has been almost
*impossible* to get the partition sizes wrong, and hence there
is absolutely no need to readjust partitions sizes (which was
indeed a *serious* admin consideration when installing a SysV R2
UNIX). Instead entire directories can be placed on other
partitions and symlinked to any given location.
For instance, in most of the multi-partition examples shown in
this thread there have been both a /tmp and a /var partition.
That is an unnecessary waste of disk space. The /var partition
is going to suffer high fragmentation, which is one reason it
should be a separate partition, but that also makes it a great
place for /tmp to physically be located. Both /tmp and /usr/tmp
should be symlinks to /var/tmp.
Other obvious candidates for locating on other partitions with a
symlink are /usr/local, /usr/X11, /opt, and where ever it is
that emacs/xemacs or tex are located.
Likewise the /home directory can actually be on one or more
other partitions. /home itself can be a symlink, but so can
each user's directory if that is useful (as might be for the
/home/ftp directory, as an example).
Hence, while it is possible to get / or /usr partitions too
small, they will be too small to even install the first time if
that is true. If those partitions are large enough to actually
manage a functional install to begin with, they *never* require
resizing.

Subject: Problem with dual EtherExpress 16 cards
Date: Sun, 25 Feb 2001 21:35:00 -0500
I am trying to use my old 486 as an internet gateway for my home network. I
have looked at the HOWTO at
http://www.linuxdoc.org/HOWTO/mini/Home-Network-mini-HOWTO.html and done
everything described there. However, I am unable to properly configure my
second ethernet card.
I am using Red Hat 7.0, and 2 ISA etherExpress 16
My modules.conf files contains teh following :
alias eth0 eexpress
alias eth1 eexpress
options eexpress io=0x300,0x350 irq=5,5
SoftSet2 (Intel's ISA configuration proggie) suggested these this
configuration.
my /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
BOOTPROTO=dhcp
ONBOOT=yes
my /etc/sysconfig/network-scripts/ifcfg-eth1
DEVICE=eth1
IPADDR=192.168.1.1
ONBOOT=1
Lastly, when I type ifconfig, I get the following output :
eth0 Link encap:Ethernet HWaddr 00:AA:00:4A:03:84

please not that I have tried other dma/irq settings for the card, all to no
acvail.
eth0 works properly, I can access the internet without problems. However,
eth1 never seems to work, even when I switch the dma/irq around.
Please, can anybody help?

Date: Mon, 26 Feb 2001 03:12:04 GMT
Hello,
I've searched everywhere but can't seem to find a solution to this problem
I'm having with my 1530P card using aha152x
I've set it in the SCSI BIOS to use IRQ 11 as my PS/2 bus mouse is on IRQ 12
and there doesn't seem to be any way on my Compaq 6150e to change it to
something else.
Still, when I load the module and explicitly specify IRQ 11, it complains of
"trying software interrupt, lost" and "IRQ 11 possibly wrong, please verify"
If I insmod it with IRQ 12, it is happy and my SCSI disk works just fine
except of course gpm complains of device/resource busy.
/proc/interrupts doesn't show anything on IRQ 11 although I understand that
it doesn't necessarily mean that something isn't using IRQ 11.
I have also tried setting the Compaq BIOS IRQ 11 as "used by ISA card" but
this had no effect (power cycle of course).
It would seem that the SCSI BIOS is the only method of altering the IRQ for
this card, although I have observed a jumper block on the card but don't
know if it is related. I know the DIP switches only affect the I/O address
and plug/play.
Anybody know what is going on here?
Thanks in advance.
