[SOLVED] Adding a new kernel to /boot partition?

Marchare · 2013-12-19 23:54:09

First of all I apologize in advance if this subject has already been brought up before. I did some researches but couldn't find anything that would answer my questions.

I would like to try Real Time (and Linux-ck later) but my /boot partition (100MB) won't let me put any file in it because there's not enough space. Here's what I got when trying to install the linux-rt package from the AUR:

{standard input}: Assembler messages:
{standard input}: Fatal error: can't write lib/ts_fsm.mod.o: No space left on device
{standard input}: Fatal error: can't close lib/ts_fsm.mod.o: No space left on device
lib/ts_fsm.mod.c:32:1: fatal error: closing dependency file lib/.ts_fsm.mod.o.d: No space left on device
 "depends=";
 ^
compilation terminated.
/tmp/yaourt-tmp-pikachu/aur-linux-rt/src/linux-3.12/scripts/Makefile.modpost:111: recipe for target 'lib/ts_fsm.mod.o' failed
make[1]: *** [lib/ts_fsm.mod.o] Error 1
Makefile:949: recipe for target 'modules' failed
make: *** [modules] Error 2

I also tried to expand the /boot partition with some livecd and Gparted but it's apparently impossible unless I completely erase it. Should I back it up and make another, bigger one or is there another solution... or maybe some element I overlooked?

Hope I was clear enough. Thanks in advance!

This looks to be a yaourt issue (it chokes on large builds unless you point it at another build dir), not the size of your /boot.

Well, I also managed to compile a vanilla kernel with the rt patchs just fine but couldn't put the bzImage file in /boot because of a space issue so I guess it's a partition issue. I probably couldn't have installed linux-rt with yaourt with the exact same reasons I couln't install with "manually".

karol · 2013-12-20 00:13:42

You can tell yaourt to build somewhere else, use --tmp commandline switch or edit /etc/yaourtrc, uncomment and change

#TMPDIR="/tmp"

to somewhere else.

You can compress the images so 100 MB should be enough.

jasonwryan · 2013-12-20 00:22:34

I have the Arch vanilla kernel and initrd and my own custom kernel in /boot and am only using 39M. 100M should be plenty.

cfr · 2013-12-20 02:01:37

I use 469M but 392M is an iso image. However, it might depend what else is there. For example, if this is an ESP created by the Windows installer, I don't know how much space Windows might take up there.

What commands did you use, and what were the actual error messages?

What is the output of `df -h`?

teateawhy · 2013-12-20 15:24:25

Retry with makepkg.

Perfect Gentleman · 2013-12-20 17:30:52

try with 'make localmodconfig'

Marchare · 2013-12-21 00:11:06

Wow, so many replies!

Sorry if my reply took long; had to yaourt the kernel again with TMPDIR="/var/tmp" in the yaourtrc config file. I got this error:

error: Partition /boot too full: 9047 blocks needed, 2048 blocks free
error: not enough free disk space
error: failed to commit transaction (not enough free disk space)
Errors occurred, no packages were upgraded.

By the way if it normal that I now find a folder called "linux-rt" that weights ~61 MiB in my /boot partition?

Also df -h gives me this (excluding other partitions):

/dev/sda5        97M   95M     0 100% /boot

karol · 2013-12-21 00:18:54

That's your partition, you should know what's there and why :-)
Are you sure you never used linux-rt kernel https://aur.archlinux.org/packages/linux-rt/ ?

jasonwryan · 2013-12-21 00:51:04

Why did you build the rt kernel in /boot? Build it somewhere else and then just copy the kernel and intrd there...

I never used linux-rt, nor any other kernel than the default one before. Because I'm completely inexperienced I most likely screwed up somewhere in the process. The "linux-rt" folder appeared in /boot after trying to install the kernel with yaourt.

According to the tutorial (written in French here) I was using as a reference one is supposed to compile the kernel, make the bzImage file then copy it along with System.map to /boot.

What exactly is in that linux-rt directory?

Here is what I get with ls:

arch	 Kbuild       Makefile		      README	      vmlinux
COPYING  Kconfig      Module.symvers	      REPORTING-BUGS  vmlinux.o
CREDITS  MAINTAINERS  patch-3.12.5-rt7.patch  System.map

karol · 2013-12-21 01:50:39

Remove the directory and all of its contents and follow jasonwryan's advice https://bbs.archlinux.org/viewtopic.php … 0#p1362490

Marchare · 2013-12-21 02:46:41

I don't exactly know what exact files initrd is referring to.

BTW should I move /linux-rt/arch/x86/boot/bzImage to /boot then?

karol · 2013-12-21 02:59:49

In my /boot I only have

$ ls /boot
initramfs-linux-fallback.img  initramfs-linux.img  memtest86+  syslinux  vmlinuz-linux

'memtest86+' and 'syslinux' are directories.

initrd is e.g. /boot/initramfs-linux.img

No. Please use the package manager for this purpose.

What am I supposed to do with the pachage manager? I will get the same error if I Yaourt the Linux-rt kernel, right?

karol · 2013-12-21 22:37:19

Why would you get any error if you clear the space that is occupied by the contents of linux-rt directory?
You don't have to use yaourt, makepkg works too :-)

With a package manager, you manage your packages. Yaourt is not a package manager, neither is makepkg. Pacman is your package manager. Makepkg is a great tool for making packages, that are then installed and managed with pacman. Yaourt is a great tool for preventing you from understanding anything that is happening in your system.

Use makepkg to make a pakage and pacman to install it.

cfr · 2013-12-22 03:06:52

Note that you shouldn't be able to build something in /boot because you should be building as an unprivileged user and /boot should only be writeable by root.

I don't even build stuff as me but I'm perhaps more paranoid than most. But I would certainly never compile code as root and neither should you.

Alright, after downloading the package from the AUR and installing the kernel with makepkg, plus fixing some issue with GRUB Linux-rt is working fine now.

Thanks everyone for your help!
