Describe draftGniarfMiniRescueDistroHowTo here.

draft - the name of the page will change, especially if it become some official coLinux rescue distribution. Edit

<Gniarf> here is a really small Busybox-based distribution in 650 ko compressed, (8 Mo filesystem uncompressed) and room to spare, with ls, cp, mount, vi... almost full list of software is here :

-sh           chown         fdformat      lsmod         sed
sh            chroot        fdisk         mkdir         sleep
bunzip2       clear         find          mkdosfs       sort
bzcat         cmp           free          mke2fs        split
unix2dos      comm          freeramdisk   mknod         swapoff
fsck.msdos    cp            gpart         mkreiserfs    swapon
fsck.vfat     cpio          grep          mkswap        sync
fsck.ext2     cut           gzip          mount         tail
fsck.ext3     date          halt          mt            tar
egrep         dd            hdparm        mv            tee
gunzip        devfsd        head          nohup         touch
zcat          df            init          pidof         tr
mkfs.ext2     dirname       insmod        pivot_root    tty
mkfs.ext3     dmesg         kill          poweroff      tune2fs
ar            dos2unix      killall       ps            umount
ash           dosfsck       klogd         rdev          uname
badblocks     du            ln            reboot        uniq
basename      dumpe2fs      loadacm       reset         unzip
bzip2         dumpkmap      loadfont      rm            wc
cat           e2fsck        loadkmap      rmdir         xargs
chgrp         env           losetup       rmmod         xxd
chmod         expr          ls            rpmunpack

and also :

more          e3            help          ldd           less
mbr           pico          strings       undeb         unrpm
vi

no network, use halt to shutdown it, use commands like mount /dev/cobd2 /mnt to mount another image...

grab it here :


distribution based on Zdisk "The purpose of 'zdisk' is to put a kernel of your choice and a rescue system on one 1.44MB or 1.722MB floppy or cdrom disk, creating a boot/rescue disk." which fits coLinux fine, since coLinux provide us with a kernel.

the core of this distribution is Busybox : http://busybox.net/ . It is licensed under the GPL : http://busybox.net/license.html , as are most of its components.


update Edit

some more info :

  • you can run this rescue disk either in read-only mode (like a CD), or in read-write mode.
  • use 'ro' in the bootparams of the colinux xml file to set the rescue image read-only - and then rather useless, except as a demo
  • do NOT use 'ro' in the bootparams of the colinux xml file to set it read/write and be able to mount another filesystem under /mnt
  • unfortunately I would like to be able to run it in read-only mode, but still be able to mount other partitions on mount points like /mnt. any suggestion is welcome here.
  • /etc/fstab and /etc/mtab are out of sync for this release - you may want to edit them a bit, otherwise, df will display nothing for /
  • exemple (from another partition, so forget the /mnt part) :
root@slackware:/mnt/etc# cat fstab
/dev/cobd0 / ext3 defaults 1 1
none  /proc  proc  defaults  0  0
root@slackware:/mnt/etc# cat mtab
/dev/cobd0 / ext3 rw 0 0
none /proc proc rw 0 0
  • (in short, tell / is on /dev/cobd0, a filesystem device and not /dev/ram0, a ram device)

Comments:

I tried using rescue_fs.bz2 with Colinux 0.6.2 but it didn't boot. What is wrong? (piyo, 2005/02/19)

Colinux 0.6.2 uses the 2.6 kernel, this rescue disk is still based on 2.4 (boiert, 2005/3/13)
