the case, assuming we already know how to do this check.
Also, while any failure mode is possible, this is not one that I recall
seeing, probably because the configuration files are mostly static. I
don't include the rpm database here because it is not static and there is
a small window of time where it is at risk when an update is being
applied. Also, we already have tools that can attempt to repair the rpm
datebase when the symptoms point to it as a problem.
Also, only deleting executable files not in the bootstrap could lead toI think if you testcase the process, you will find that the files that my

method would not delete are mostly application specific user files and are
not going to affect whether or not the Package Manager runs correctly.
The way I look at it is that these files are there for a reason. While
reinstalling the bootstrap might not replace them immediately, they will
be replaced, often with he same identical file as the user installs the
packages the the bootstrap reinstall implicitly deleted.
To say it another way, my POV is that the goal of reinstalling the
bootstrap is to put the Package Manager back into a working state while
minimizing the number of files that get deleted which might contain user
specific data. Any leftover cruft can and will be taken care of as the
packages "lost" by the bootstrap reinstall are reinstalled.
however, if we are keeping theI never considered doing this. It's a bad idea. The bootstrap db will
become the working db. There may be extra files left in the directories
managed by the Package Manager after the unzip, but the chances of these
files causing the Package Manager to fail is minimal If it turns out
there are exceptions, then they can be added to a must delete list.
The question that needs to be answered is if I unzip the bootstrap onto an
arbitrary working or broken Package Manager setup and overwrite any
conflicting files with the files from the bootstrap zip, do I get a
working Package Manager. If I do, then I have accomplished my goal.
Bringing everything else back to the state it was before the bootstrap
reinstall was required will be normal Package Manager operations.

Thinking about this.True. The sypmtom is, as you say, every other recovery solution failed.
The troubleshooting wiki essentially lists symptoms and solutions.
Re-bootstrapping isn't a symptom but an operation.

working grep because everything it needs will be installed.
Good.One of my goals in working the stunnel issue with Massimo was to make the
idebug-small package as user-proof as possible. Roderick and I had
already used an early version of the package to track down a couple of
application failures, but Roderick does not need to be spoon-fed when
doing this kind of stuff. He recognizes and error message when he sees

override the default bread crumb text. I suspect most folks will not even
notice the somewhat redundant text.
Having thought about the bootstrap reinstall issue some more, the curent
processing sequence I envision is:
- Verify that the user has shut down any non-essential
- Confirm that the user is really really sure he/she
wants to do this.
- Use psfiles to capture a list of open files in the directories
managed by the Package Manager.
- Unlock the files.
- Alert the user if one or more files cannot be unlocked.
These will be data files.
Exactly how to handle them is TBD.
It really depends on the specific locked file.
- Save any files we decide need to be saved.
yum.log -> yum.log-orig etc.
- Download the bootstrap.
- Unzip the bootstrap overwriting any existing files.
This should result in working Package Manager.
If we want to be really nice, we could offer to convert the saved yum.log
into a list of packages the need to be installed because they were
logically uninstalled during the bootstrap reinstall. The normal ANPM
update process will take care of the packages known to the bootstrap.
