Put a stern README file in log and seg0 directories to warn users of corrpution
they will cause if they touch files there

Key: DERBY-5232
URL: https://issues.apache.org/jira/browse/DERBY-5232
Project: Derby
Issue Type: Improvement
Components: Store
Affects Versions: 10.8.1.2
Reporter: Kathey Marsden
Users often on bad advice or desperation touch or delete files in the log or
seg0 directories (mostly log).
I think it would be good for new databases and on upgrade that a file be
created in these directories with a name like:
TOUCHING_FILES_HERE_WILL_CORRUPT_DB_README.txt
or some such to warn of the perils of doing this and the corrupting effects and
how it can eliminate any possibility of salvage. It should also encourage users
to make a zip backup of the database directory with no jvm currently accessing
it before trying to do anything with the database if it appears to be already
corrupt. Also point to backup/restore documentation and encourage restore of a
good backup into an empty directory if the database is corrupt.
I'm not sure if it would help but it couldn't hurt.
