And as most Linux users tend to have their installation divided into
partitions, such as /home, /var, /usr, /temp, /boot, etc that part would
be irrelevant.

I do wonder if that is true these days for "most".

Well to qualify that, I'll say the Linux users that I know & those in the
local LUG. I have seen too, many linux users online who advocate
partitioning the drive as above, or similar.

I for one haven't really (yet) bothered with that for my fairly simple
home uses. But I've never been particularly concerned by using discs
that aren't 'defragged' since RO systems don't bother with that either!
:-)

I've always had at least a /home partition, so that when I want to either
change a distro or do an upgrade, my personal data isn't disturbed.
I occasionally run 'fsck' too, to check the filesystem.

I also wonder what relevance this may have if we drift to using solid
state HDs. Both of my new machines do so. Not conventional 'spinning
disc' HDs at all in normal use. Given what is said about such discs
having a finite write history perhaps defragging is a bad idea for them?

Well as far as defragging goes, it's not need in Linux so that
issue doesn't arise. Dunno about Windows though, I suppose defragging
could be detrimental to the SSD.

However to extend the life of an SSD in Linux, you can use the ext4
filesystem, but turn off the journaling function. You could also enable
TRIM support, but you'd need a kernel that supports it. uname -a will give
you your kernel version, & if it's 2.6.33 or higher then your kernel will
support TRIM.

There's a lot on here about it.

I can see that it makes sense, particularly if the user like to keep
up-to-date with their distro and/or change. Alas, it didn't occur to me
when I started out, and TBH I'm happy so far with the disros/versions I
settled on last year. So as yet I've not bothered to change.

May well start using partitions more sensibly when I decide to do a major
upgrade of distro/version. Current situation is simply a product of my
initial ignorance!

Below 2.6.33. for my laptop. So I guess not at present.

Thanks for the above info. I'll have a look, but by default I'm currently
assuming I don't need to worry about this at present. The laptop I use for
general purposes has 3BG of RAM and never really seems to need the swap
partition, and I probably don't do a shedload of data writing.

I'll check this out, though.

TBH my main interest in the kernel and modules, etc, is the hope that one
day I'll actually *understand* the sound system properly! :-)

Slainte,

Jim

I would agree.

The laptop I use for general purposes has 3BG of RAM and never really
seems to need the swap partition, and I probably don't do a shedload of
data writing.

I once made a mistake when testing a distro I'd installed on another HDD.
I had 4GB RAM installed but I'd clean forgotten to add a swap partition!
The distro worked just fine, & it was only after a couple of weeks I
discovered my error. After some research, I found that Linux uses memory
more efficiently than Windows. I notice some newcomers to Linux often ask
why is the OS using all their RAM. Your computer is using all of your
memory to optimize the performance of Linux. It caches or stores pieces of
applications on your memory so that when you need them, it will not have
to hunt around the hard drive to find the application. Now IF you bring up
a program, and your memory is "full" Linux automatically kicks some of the
cache out to make room. It is a fast-as-lightening operation that does
nothing but make Linux optimized and faster.
A couple of my machines have 16GB RAM, & although I can have OpenOffice,
Pan,Claws-mail, Gimp, k3b (disk burner), Pidgin (Instant Messanger) open &
in use, the swap partition is hardly used.

I'll check this out, though.

TBH my main interest in the kernel and modules, etc, is the hope that
one day I'll actually *understand* the sound system properly! :-)

Good Luck! :-)
