Re: How to fix ldso? Urgent.

[Lindsay Allen <allen@cleo.murdoch.edu.au>]

Hi Joost,

Success!  

This is what I had to start with:- 
elm# cd /lib ; ll ld*
-rwxr-xr-x   1 root     root       161677 Jun  5 21:35 ld-2.0.4.so*
-rwxr-xr-x   1 root     root        22305 Jul 19 03:13 ld-linux.so.1.8.10*
lrwxrwxrwx   1 root     root           11 Jul  3 18:19 ld-linux.so.2 -> ld-2.0.4.so*
-rwxr-xr-x   1 root     root        20640 Mar  4 01:42 ld.so*
-rwxr-xr-x   1 root     root       103272 Jul 19 03:13 ld.so.1.8.10*

I still had some functionality - the bash internals worked, mount and cp
worked, so after a long look at your message I:-
  on another box, extracted ldso_1.9 to a floppy
  mounted the floppy in my box
  cd /lib
  cp /floppy/lib/ld-linux.so.1.9.2 .
  ln -s ld-linux.so.1.9.2 ld-linux.so.1

This left me with:-

elm# ll ld*
-rwxr-xr-x   1 root     root       161677 Jun  5 21:35 ld-2.0.4.so*
lrwxrwxrwx   1 root     root           17 Jul 23 08:52 ld-linux.so.1 -> ld-linux.so.1.9.2*
-rwxr-xr-x   1 root     root        22305 Jul 19 03:13 ld-linux.so.1.8.10*
-rwxr-xr-x   1 root     root        22257 Jul 23 08:50 ld-linux.so.1.9.2*
lrwxrwxrwx   1 root     root           11 Jul  3 18:19 ld-linux.so.2 -> ld-2.0.4.so*
-rwxr-xr-x   1 root     root        20640 Mar  4 01:42 ld.so*
-rwxr-xr-x   1 root     root       103272 Jul 19 03:13 ld.so.1.8.10*
elm#

I installed a small package with dpkg to see how it went and then 
dpkg -i .../ldso_1.9.2-3

and it all seems fine.  I didn't even lose my net connection.

Many thanks, Joost.  I hope that I carried out the intent if not the
letter of your suggestions.  I owe you one.

I have a spare partition here and much spare time so any time you want a
destructive test carried out, pehaps along the above lines, I am quite
happy to oblige. Putting Debian back on from my cdrom (thank you, LSL) is
a breeze. 

Lindsay
