Description of problem: When I boot with the Rescue CD and try to run simple
commands it gives me error messages about incompatible .so files or unresolved
references. For example, simple tools such as vim won't launch.
Version-Release number of selected component (if applicable):
How reproducible: Always
Steps to Reproduce:
1. Install Fedora 6. I suspect that part of the problem is my installation
configuration; I put the OS on HDA by itself (in a Linux partition, not a
logical volume) and put all of the data on a large LV.
2. Boot from the Rescue CD; all commands work.
3. yum -y update
4. Boot from the Rescue CD
Actual results: Many simple commands fail (vim, pvdisplay, etc.). Clearly, the
Rescue CD is reading .so files from the hard drive rather than from the CD.
Expected results: After booting from the Rescue CD, all commands should work
regardless of the installed OS version or the updates that have been made to it.
The Rescue CD should never depend on the installed OS to resolve dependencies.
Rescue mode doesn't actually provide all that much stuff. Things like vim and
pvdisplay are actually being found on the installed system. You can use which
to check that. If you look at $PATH, you'll see we put the installed system
binary directories at the end. You'll also see the same thing going on with
$LD_LIBRARY_PATH. We append to the end of that so the installed system programs
can still work.
Are there specific programs that come with rescue mode that are looking on the
installed system for libraries?
Well, certainly 'vim' and 'pvdisplay' are good examples. Both work if I boot
from the hard drive, worked from the Rescue CD prior to 'yum -y update', but
fail when run from the rescue CD after the update. If you need to use the
Rescue CD, then 'pvdisplay' is certainly one of the things you are likely to use.

insatlled f9, did an updates and ran vgdisplay. it seems to be there. Vim is
not there but vi is. For the rescue image we dont have a lot of space, and that
is the main reason we dont include a whole lot of stuff in there. The rescue cd
would be a tool to do very basic things, "all commands" in this case will not work.
Additionally there are alternatives that better fits the needs of the user that
wants more applications working on a "rescue situation". Fedora liveCD can be
of great help in these cases.
Moreover, the user can customize the CD and have user defined applications in
the "rescue environment"
I'm going to mark this as NOTABUG because the overall objective of rescue is far
away from having *all* the commands work.
