LOL.* I have to admit, I didn't think about things like video. _video_ never
goes to /tmp on my system.* Specifically because it always wants to use a
lot more space than I have in /tmp.

I used to make a really, really,
big swap partition, and put /tmp in tmpfs
(ie, it uses part of the swap).* Then I figured I wasn't really wasting
space.* But Ubuntu bollixed that and I never got around to fixing it.

No, a swap "filesystem" is a fixed length, and resizing it changes it.
Resizing some
real filesystems would probably do the same.

oops. :-)

2**32 is _still_ a very big number.* There are almost certainly not 4
billion vfat filesystems in the world today.

Yay! A solution for the kernel 'improvements' and the udev virus! Have
to do it by hand, it sounds like, but maybe it'll work.

| UUID is all you need to identify it!* You just put it in the fstab.

it?

Disk controller software used to call SCSI drives sda... and the IDE's
hda... When I set the SCSI ID to 0 on my system (boot) disk,
it'd be
called sda -- all the time -- and grub's menu.lst and fstab would never
have a problem. When I bent something, I could at least boot the system
and fix it.

Then somebody had the brilliant idea of calling everything sd... Now
whatever is scanned first, SCSI, IDE, SATA, USB sticks, whatever, gets
called sda. Very poor.

udev was supposed to fix this, I think. But the installer(s) don't build
the rules, so when I installed Heron on my Mac Pro the other day, then
turned on an external SCSI disk, then updated Ubuntu's kernel, I got to
reinstall Ubuntu.

It looks like Ubuntu's got fstab fixed and menu.lst sorta fixed (it
still refers to the BIOS' (hd0,1) -- don't know, but that may be a
problem with grub). Getting there...

I would hope not, but you never know.* There are a lot of USB sticks out
there.* Give everyone in the world one and you have more than 4 billion!

I've been googling, but can't seem to find a definitive answer...* Can
I install 32 bit Ubuntu on a 64 bit Xeon machine?

Specifically, in case it matters:

Supermicro MB X7DBE
2x Xeon E5430 2.66GHz Quad Core

Greetings,
I am trying to install Gnucash 2.2.6* and get a configure check error.

------------------------------------------------------
Package gconf-2.0 was not found in the pkg-config search path. Perhaps
you should add the directory containing `gconf-2.0.pc' to the
PKG_CONFIG_PATH environment variable No package 'gconf-2.0' found
configure: error: Library requirements (gconf-2.0 >= "2.0") not met;
consider adjusting the PKG_CONFIG_PATH environment variable if your
libraries are in a nonstandard prefix so pkg-config can
find them.
--------------------------------------------------------
There is no gconf-2.0.pc in /usr/lib/pkgconfig. In fact I could not find
it anywhere on my system. Also, /usr/local/lib/pkgconfig is
empty.* If I
need to set a symbolic link to some .pc in pkgconfig, I don't know which
one.* Can I make my own gconf-2.0.pc file? Any ideas?

Mike

A while back somone on this list suggested loading and reading Rutebook.
As far as I am
concerned that was a stroke of geniouse.* It is the best
tutorial I have ever read on any technical subject.* It is straight to
the point and doesn't explain anything that doesn't need to be known for
the particlar subject being* read at the moment.* Evey little shor
unmemorable two and three letter command has had it's meaning spelled
out so you have a reference to remeber by.* I find it's much easyier to
rember for example "change diectory than CD.* I can't get my mind around
cd it's not anchored to anything. But the biggest thing I learned is
that in the past I have read something and felt dumb if I didn't
understand it. He lets you know to read everything three times, do the
exercise and don't move on until you know the subject.
* * I have been reading off and on a couple days for a total of one good
days reading and have learned more than I have in all the
reading I have
done on linux put together. I haven't learned a lot but what I have
learned," I KNOW."* One thing* I think I have found is I am not just
dumb ,this stuff is hard.* I can't stress enough how good this tutorial
is for newbies.
* * * * * * * * * * * * * * * * * * * * * * * * * * * * * * Doug


Doug:
Thanks and since I missed it would someone post the location again for I really need to read study this
And while we are on newbies and I am certainly one linux and ubuntu suddenly became more organized when len suggested I switch to


[kubuntu] desktop. Maybe its just me, but suddenly I had a place to put things and knew where to look.
I normally read everything here and it has made a huge difference.
Thanks to all

Okay, I'm game, do I need a special pair of glasses for this invisible ink?

Install the package "rutebook". The installed files are in the
directory "/usr/share/doc/rutebook". You can start reading the html
version at "/usr/share/doc/rutebook/html/index.html" and there is a pdf
version, too.
