Minimal install

Slax-Dude · 09-24-2009, 04:00 AM

Well, grep is used on the init and network scripts, so I cant do with out it.
bzip2 and diffutils are needed for slackpkg.
findutils I'm unsure... haven't found any major scripts with "find" or "xargs" in them.

The rest of them I'll remove (one by one) and see if it brakes stuff

If kernel-modules is not needed it would be great since it's a 15Mb (compressed!) package!

I'll keep you guys posted

Thanks for the tips

gnashley · 09-24-2009, 05:07 AM

find is optional during startup -if present, it is used when looking for updated kernel modules. 155MB is still about 100MB too much -but your filesystem block size may be affecting the size too.

OK, here is what was left after I removed some packages as gnashley suggested:

Code:

aaa_base-13.0-i486-2

bzip2-1.0.5-i486-1
coreutils-7.4-i486-1
devs-2.3.1-noarch-25
dhcpcd-3.2.3-i486-1
dialog-1.1_20080819-i486-2
diffutils-2.8.1-i486-3
e2fsprogs-1.41.8-i486-1

network-scripts-13.0-noarch-2
openssh-5.2p1-i486-1
openssl-solibs-0.9.8k-i486-2
pkgtools-13.0-noarch-3
procps-3.2.7-i486-2
sed-4.1.5-i486-1
shadow-4.0.3-i486-18
slackpkg-2.80.2-noarch-3
sysklogd-1.4.1-i486-10
sysvinit-2.86-i486-6
sysvinit-functions-8.53-i486-2
sysvinit-scripts-1.2-noarch-30
tar-1.22-i486-2
udev-141-i486-3
util-linux-ng-2.14.2-i486-1
wget-1.11.4-i486-1
which-2.20-i486-1
xz-4.999.8beta-i486-1

Note1: The filesystem is ext2 and has a block size of 1024
Note2:

kernel-modules could not be removed --> lost network

procps could not be removed --> rc.d scripts need "ps" and "killall"

findutils could not be removed --> removepkg needs it

The grand total is 140Mb

Good list, the differences between 12.2 and 13.0 are quite small, my list allows you to compile and use sbopkg, and yours allows you only to use slackware packages, but that is cool because you would then be able to download the extra packages you need.

You have added four packages, iputils, openssh, sysvinit-functions and xz. I can see the definite need for xv, the probable need for sysvinit-functions, but you might be able to remove the other two, though this is just a guess as I haven't tried it.

You should be able to remove slackpkg as that only allows you to update your system and you can to that manually with wget.

I would add a boot loader or you will not be able to access your system on a fresh install, lilo ?

I need iputils to have network (tools like ifconfig are in that package).
I also need to login remotely to add some packages or change some .conf files if needed, so openssh must be there as well.

Indeed I can, but since it's only 180Kb (uncompressed) and I love the simplicity of "slackpkg update" + "slackpkg install d" to get me a compiling machine like yours, I'll let it stay

I'll use wget for non-standard stuff like sbopkg

I usually install the bootloader (I prefer grub) during the installation process and not as a package on the newly created machine.
I mean: if I install 10 slackware systems into the same HD, they don't need all to have grub installed.
Like the slackware installer, I'll leave the bootloader as optional, as it may not be desirable to install it.

My goal is to build a sort of slackware-template that once installed could be easily expanded in to a full slackware installation or a custom slackware installation like a dedicated mysql server or a web server.

Whatever the final system may become, it would start with the same template.

I was asking myself this same question a few years ago and came across this page : Slackware : The boot process.. Not sure how up to date this will be now (Version 10 is mentioned, but I still look at it now and again to remind myself of what is going on with my various boxes (all now on Slack 12.1 or 12.2) at boot time. I find it nice and short and to the point.

Slax-Dude:

If I use your install. I get this error: No inittab file found.
Then it ask me what runlevel I want to boot

I type 3 and then it says: no more processes left in this runrevel.

You have probably forgot something

gnashley · 10-03-2009, 03:04 AM

That would be the sysvinit-scripts package.

Kowalczyk · 10-06-2009, 03:32 AM

dont you need the kernel-firmware as well?

Ehhm.

I installed the packages just from A series
In the guide.
I also added Lilo to have a bootloader.
But Im still 276MB in use.

Why?

Is it because of ext4
Maybe I'll try ext3 and see what happens then

I tried ext2 with lilo and that gave me 149M
so Ext4 is a lot bigger

gnashley · 10-06-2009, 05:56 AM

Any journaling filesystem is going to add a lot to the size as expressed by disk usage utilitie.

Kowalczyk · 10-06-2009, 06:48 AM

I get chroot cannot execute /usr/bin/passwd: no such file or directory. what packages includes that? I have etc,etc,sed,shadow
I cant figure out what package I forget to install.

This is under the install when I'm prompted to setup root password

Didier Spaier · 10-06-2009, 07:07 AM

Code:

bash-3.1$ grep "usr/bin/passwd" /var/log/packages/*
/var/log/packages/shadow-4.0.3-x86_64-18:usr/bin/passwd
bash-3.1$

HTH,

Kowalczyk · 10-06-2009, 07:54 AM

I know. and I have selected shadow. but I still get that error. so I cant figure it out

what else I am doing wrong.

http://dump.no/files/c89ed3154d9f/slackware.JPG
This is the most minimal I have managed.
that worked

the same with ext2 would be 149 mb.

so what can I remove there?

gnashley · 10-06-2009, 08:10 AM

Remove aaa_elflibs to save a little space. It will also make your list more accurate -you may be running some programs which depend on libs which are included in aaa_elflibs but don't have the regular package for them installed. What I mean is this: aaa_elflibs contains duplicate single libraries which are each contained in some other package. if you really want to know which packages are essential for your purposes, removing aaa_elflibs will help you find that out, and it will eliminate other libs in there which you do not need.

I have a little tools here:
http://distro.ibiblio.org/pub/linux/...3-noarch-1.tgz
which will save you some space by removing unwanted language files. Even if you have not installed glibc-i18n, most packages install their own language files.

Another trick you can use, which Patrick used to do when building the zipslack distro, is to remove all header files under /usr/include and also all static libraries under /usr/lib

Code:

cd /
find usr/include -name "*.h" |xargs rm -f
find usr/lib -name "*.a" |xargs rm -f

Of course, this removes files while not removing them from the package database, so later removing/upgrading the packages will show error messages.
You'll also find there is lots of 'cruft' under /usr/doc...

The localepurge script above will remove several hundred MBs from a full install!

samac · 10-06-2009, 08:11 AM

pkgtools and dialog are not needed for the system to boot, they are for administration.

Maybe?
