Default installation doubt

Hi,

I am coming directly from Windows XP, though I was not a windows admin but I have with my Ubuntu LTS 10.04 CD. Planing to install this in the hope that it is becoming the most popular distro. Said that, please let me know if during installation, what should I do:



Create the separate partitions for each /, /home, /tmp, /usr etc....or not? Though its just a newbie talk, but at least I know the installation but don't know if should install separate each identities or not....?



Regards,
BB

I'm sure you will get replies to set up separate partitions for
everything. Which is probably a pretty good idea actually. I usually
just let the installer do whatever it does. Seems to work out just fine.


If I'm dual booting with Windows on a machine I use Windows to partition
off however much of the hard drive I want to give Linux. My thinking is
that Windows knows best how to deal with making sure it's files are safe
afterwards. Whether that's true or not, I don't know. Then when
installing Linux I tell the installer to use whatever space I've set
aside and let it run. As I said, it seems to work just fine for me. So
far I've had very few issues.

All you need is:

/
/home
swap

Leave all the rest in `/`. Decades ago on big Unix servers they were
helpful, but not any more, not when you can just boot a computer off a
CD into a full graphical Linux desktop and fix things that way.

Having /home separate means that you can share it between multiple
distros, or wipe & reload one distro without fear that you will lose
your data. That's why I recommend keeping it separate.

You don't need much space for the / filesystem. 8GB is enough for most
people, 16GB is generous and 32GB is profligate.

There used to be a good argument for having a separate partition for
/home so that you could re-install a later version of Ubuntu and keep
the home data partition. This is no longer necessary as it is
possible during installation to tell it not to overwrite /home by
telling it not to format the partition. I just use a single partition
(plus swap).

I have just seen Liam's point that if you want to try an alternative
distribution then separate /home may be a good idea, which may well be
valid if you were thinking of doing that.

This is true, I hear.

*But* there are multiple drawbacks:

* You can't install a different, non-Ubuntu distro that way.
* You can't share /home between different distros in a multiboot
arrangement that way. (E.g. it's very nice to be able to install the
*next* version of Ubuntu for a test-run before you commit to upgrading
your main install.)
* You can't put /home on a bigger drive that way.
* You can't put *just* / on a fast SSD or something.
* If a disaster corrupts your / partition, you lose all your data as
well. (E.g. if you tried to resize it and it went wrong.)
* It makes it more difficult to backup just your data.

And of course when reinstalling you have to trust that it will leave
your data alone. I don't like taking chances like that if I have a
ready alternative.

I thin k the arguments for splitting off /home are very strong, myself.

that can get you into awkward situations where apps use different
mechanisms for storing their settings, i really wouldnt count on
userspace to work properly if you share home between distros (or even
different releases of the same distro) once they excpect a certain
setup in your home dir ...
there are weeks of work of an ubuntu development cycle going into
making sure that forward transitions of app settings work for users ...

i.e. if the evolution folder format changes and there is a conversion in
the background going on on first startup of the newer evo you might not
be able to reach your mail with the older one (you could replace
evo with firefox, libreoffice etc above) ... so be careful with shared
home...

And of course, the really geeky way to have multiple distros installed
at once on a suitably large hard drive (or bunch of them) is to have a
small /home for each with symlinks to the common stuff
like /home/Documents, /home/Music and /home/.local/share/ which are
actually on a large common /data partition somewhere.

This is actually kind of fun to set up and makes it easy to evaluate/use
several distros at once without worrying about coordinating data.

Probably much more than the OP wants at this point though.

You are mistaking 2 different concepts.

A shared *home directory* is not the same thing as a shared /home filesystem.

My home _directory_ is /home/lproven but it is on my home _filesystem_
which is /dev/sdb6.

He isn't, as I understand it.

My home _directory_ is /home/lproven but it is on my home _filesystem_
which is /dev/sdb6.



He's not talking about that. He's talking about the .evolution, .local,
.config files etc that are in your /home/lproven directory. Sharing
those dot folders between multiple releases / distros is unwise.
