I've been thinking about discontinuing the use of GNU Coreutils on my Linux systems, but to be honest, unlike many other GNU components, I can't think of any alternatives (on Linux). What alternatives are there to GNU coreutils? will I need more than one package? Links to the project are a must, bonus points for naming distro packages.

Also please don't suggest things unless you know they work on Linux, and can reference instructions. I doubt I'll be switching kernels soon, and I'm much too lazy for anything much beyond a straightforward ./configure; make; make install. I'm certainly not going to hack C for it.

warning: if you're distro uses coreutils removing them could break the way your distro functions. However not having them be first in your $PATH shouldn't break things, as most scripts should use absolute paths.

Curiously, why you looking for alternatives? –  Tshepang Jan 20 '11 at 14:11

@xeno "More robust"? Also keep in mind that your system (including kernel) is largely built with GCC and depends on GLibC :) –  Tshepang Jan 20 '11 at 14:24

@xeno Debian is actually now using EGLIBC, which sort of a fork of GLibC. But it follows GLibC closely, so the diff ain't that big. –  Tshepang Jan 20 '11 at 14:41

Both Clang and tcc could (at one time, anyway) compile the Linux kernel. –  Shawn J. Goff Jan 20 '11 at 15:01

There are people working on a GNU userland on a BSD kernel, but I haven't heard of the other way round. Really switching kernels would be easier. You can try it first in a VM if you're shy. –  Gilles Jan 20 '11 at 21:36

busybox the favorite of Embedded Linux systems.

BusyBox combines tiny versions of many common UNIX utilities into a single small executable. It provides replacements for most of the utilities you usually find in GNU fileutils, shellutils, etc. The utilities in BusyBox generally have fewer options than their full-featured GNU cousins; however, the options that are included provide the expected functionality and behave very much like their GNU counterparts. BusyBox provides a fairly complete environment for any small or embedded system.
BusyBox has been written with size-optimization and limited resources in mind. It is also extremely modular so you can easily include or exclude commands (or features) at compile time. This makes it easy to customize your embedded systems. To create a working system, just add some device nodes in /dev, a few configuration files in /etc, and a Linux kernel.

You can pretty much make any coreutil name a link to the busybox binary and it will work. you can also run busybox <command> and it will work. Example: if you're on Gentoo and haven't installed your vi yet, you can run busybox vi filename and you'll be in vi. It's

feel free to modify this with links to your distro –  xenoterracide Jan 20 '11 at 14:20
    
also, this is a favorite on embedded, so though an alternative it's probably not going to be enough to replace GNU for my desktop/server environment –  xenoterracide Jan 20 '11 at 14:27
    
This is the only practical solution atm, if you don't want to hack C. And busybox versions should be pretty standard conforming. –  maxschlepzig Jan 21 '11 at 21:25

This is an older topic, I realize. However, this solution was never mentioned and comes up relatively high on google for "Linux with bsd userland".

There's another solution: heirloom. I know it works on Arch, and it's packaged in the AUR (look at gnu2sysv, for instance). This will replace Arch's coreutils package and provide the heirloom equivalents. You can read about the whole thing on arch's wiki: https://wiki.archlinux.org/index.php/Base2heirloom

I suspect you'd have a hard time getting rid of GNU Coreutils, however, there's always the equivalent BSD tools, although they aren't drop-in replacements for the GNU tools.

how would I go about installing BSD tools on a Linux distro? where would I get them? –  xenoterracide Jan 20 '11 at 14:22
    
FreeBSD's entire OS is available via CVS freebsd.org/cgi/cvsweb.cgi/src, however, getting the BSD userland to compile under a Linux kernel would be rather difficult. GNU's userland is probably more portable than BSD, since GNU's userland (at least at the beginning) was built to be portable between multiple kernels. –  jsbillings Jan 20 '11 at 15:32
    
that sounds like a PITA, sure if it's reasonably possible someone somewhere has packaged it at least once for linux. –  xenoterracide Jan 20 '11 at 16:46
    
Solaris (as of 140-something is also available) would also be an option. If you are using a distro you are crazy. Stop now. If you are using LFS, rock on! Have fun! If you are making a distro, I applaud your bravery sir. –  bahamat Jan 20 '11 at 16:49
    
Yeah, I'm not sure it's even possible. It'd probably be easier to just install FreeBSD and enable linux compatibility. You can easily get the GNU coreutils working under FreeBSD, but not vice-versa. –  jsbillings Jan 20 '11 at 16:53

Solaris (as of svn_140-something) would also be an option.

If you are using a distro you are crazy. Stop now. Seek psychiatric help.

If you are using LFS, rock on! Have fun!

If you are making a distro, I applaud your bravery sir.

this isn't a question about "which distro" can I use, it's about replacing coreutils on Linux. Unless you're referring to opensolaris coreutils? also is this less of a PITA than the FreeBSD option? –  xenoterracide Jan 20 '11 at 16:56
    
The source code for OpenSolaris is just Solaris. The Solaris source code up until svn_14x was released by Sun/Oracle under CDDL. There are basically three main heritages for Unix userland. "Genetic" Unix (Solaris, AIX, True64, etc., which came from AT&T code and is largely closed, but Solaris was open for a time), BSD (which finally stood on it's own as of 4.4-lite) and GNU. But I think that moving away from GNU will be equally difficult (or easy) wether you go with BSD or Solaris. Or you can get really ambitious and make xenocore-utils ;-) –  bahamat Jan 20 '11 at 17:06
