Revision as of 07:39, 7 December 2012
The base2busybox project aims to offer drop-in replacements for various central parts of the Arch linux base system.
IMPORTANT: Do not expect 100% drop-in replacement and compatibility. Certain utilities may not exist and for those that do, there may be missing options. One purpose of this Wiki is to document missing features and the problems they cause (in order to device work-arounds). Make sure that the replacement(s) that you install fill your needs before proceeding.
Busybox commands are simply symlinks to the busybox binary and are thus extremely light weight. For a low footprint system, this could be quite valuable.
Contents
gnu2busybox-coreutils
Package gnu2busybox-coreutilsAUR offers a nearly pain-free drop-in replacement of the GNU coreutils. Some commands lack options present in the corresponding coreutils binaries.
Gain from replacing coreutils with busybox: GNU coreutils: 13.1 MB installed, symlinks to busybox: approximately 0.
Missing utilities:
/bin
dircolors
/usr/bin
chcon csplit factor fmt join nl nproc paste pinky pr ptx runcon shuf
stdbuf timeout truncate tsort users
Missing utilities that are mapped to corresponding Busybox functions or ash script files
/bin
dir --> ls shred --> rm vdir --> ls
/usr/bin
link --> ln unlink --> rm sha224sum --> script: perl-digest-sha sha256sum --> script: perl-digest-sha sha384sum --> script: perl-digest-sha sha512sum --> script: perl-digest-sha
Missing features that cause problems:
readlink: missing option [-e, -m, -q or -s] causes problems for Yaourt
base2busybox-util-linux
Package base2busybox-util-linuxAUR offers an alternative to util-linux.
Gain from replacing util-linux with busybox: util-linux: 7.5 MB installed, symlinks to busybox: approximately 0.
Missing utilities:
/bin
arch findmnt lsblk
/sbin
agetty blkid cfdisk ctrlaltdel findfs fsck.cramfs fsfreeze fstrim mkfs mkfs.bfs mkfs.cramfs raw sfdisk swaplabel wipefs
/usr/bin
chkdupexe col colcrt colrm column cytune ddate fallocate i386 ionice ipcmk isosize line look lscpu mcookie namei pg rename scriptreplay setterm tailf taskset ul unshare uuidgen whereis write x86_64
/usr/sbin
addpart delpart ldattach partx tunelp uuidd
Missing features that cause problems:
gnu2busybox-findutils
Package gnu2busybox-findutilsAUR offers functionality corresponding to the binaries found in GNU findutils.
Gain from replacing findutils with busybox: GNU findutils: 1.7 MB installed, symlinks to busybox: approximately 0.
Missing utilities:
/usr/bin
oldfind
Missing features that cause problems:
gnu2busybox-diffutils
Package gnu2busybox-diffutilsAUR offers functionality corresponding to the binaries found in GNU diffutils.
Gain from replacing diffutils with busybox: GNU diffutils: 1.4 MB installed, symlinks to busybox: approximately 0.
Missing utilities:
/usr/bin
diff3 sdiff
Missing features that cause problems:
FUTURE PLANS
- Busybox-init: a very simple (only 1 runlevel) init system, ash init scripts
- Meta-package and/or group to easily convert an Arch base system to a busybox base system.
