I decided to try this way first. |
| 30 |
|
| 31 |
I've got a problem on the way and hopefully restored the system. |
| 32 |
The problem appeared after downloading and extracting new bash: |
| 33 |
wget |
| 34 |
http://tinderbox.dev.gentoo.org/default-linux/x86/app-shells/bash-3.2_p39.tbz2 |
| 35 |
tar xfpj root/All/bash-3.2_p39.tbz2 |
| 36 |
|
| 37 |
Every next execution of bash (and sh also) gave me: |
| 38 |
colinux ~ # sh |
| 39 |
sh: /lib/libc.so.6: version `GLIBC_2.4' not found (required by sh) |
| 40 |
|
| 41 |
I didn't get through it, but rather restored the partition from backup. |
| 42 |
By the way, does one know a windows tool, that can write a partition directly? |
| 43 |
|
| 44 |
If one is interested, I managed to get this way: |
| 45 |
I had the backup on the windows host system. |
| 46 |
I replaced my root's shell with /usr/bin/python and wrote a script that did |
| 47 |
what "cat > /dev/cobd/4" would do if it was available. |
| 48 |
The I restored the system running the following: |
| 49 |
$ gzip -d < /z/inst/colinux/colinux20090512.img.gz | ssh root@colinux -C |
| 50 |
'execfile("cat.py"); cat("/dev/cobd/4")' |
| 51 |
|
| 52 |
It's really funny, but writing these lines I've understand that I had mounted |
| 53 |
host file system, and I could have restored the backup through it. |
| 54 |
|
| 55 |
|
| 56 |
Have a nice time ;) |

Alexey. |
