How to edit /proc/version?

DarkCerberus · 2013-09-10 13:41:30

Hi,

I'm just curious in asking how is it possible to change the kernel string in /proc/version - I've tried to change it countless times but can't all I get is "Unexpected error: Error writing to file: Input/output error" - what must I do to change the 3.10.10-1-ARCH to let say 3.10.10-1-CUSTOM?

This has been bugging me for the last few weeks, and I've tried doing searches on google but failed - can anybody help.

It might help if you state why you would want to do such a thing?

I'm wanting to practice in making my own distribution that's all, but the only thing is I can't edit the /proc/version - You could say I prefer doing things very technical with Operating Systems and since linux is free why not attempt at creating my own since it's possible.

/proc is a pseudo-filesystem, it gets recreated on boot, so removing / editing files from /proc is futile.
/proc is for reading stuff from.

In addition to this, many files (though I am unsure of /proc/version) in /proc are not actually files, they are pseudo-files which are populated on being read or opened. As a result, for many of the files in /proc, editing them will do nothing.

All the best,

Have a look at https://projects.archlinux.org/svntogit … ages/linux

pkgbase=linux               # Build stock -ARCH kernel
#pkgbase=linux-custom       # Build kernel with a different name

a random uname from linux-ck kernel: https://bbs.archlinux.org/viewtopic.php … 5#p1205835
If this is what you want, have a look at https://aur.archlinux.org/packages/linux-ck/ and the wiki on how to make custom kernels.

That -ARCH part is set during kernel compilation, it's set by CONFIG_LOCALVERSION in .config. As far as i know, you can't change it in already-compiled kernel.

Where did you get the idea that editing /proc/version will help you with such a large project? I'd suggest you start at the beginning by reading some of the copious relevant documentation that's available to you, instead of randomly poking at stuff that you clearly don't understand.

If you use an arch kernel, then this is included in the version string. I don't understand why you want to change it. If you want to create a custom (meta)-distribution, the distribution name, version, ... are defined in /etc/os-release and maybe /etc/DISTNAME-release
