[OpenAFS] problems with file links under Windows XP
Thu, 24 Jan 2008 15:44:22 +0100
I try to produce a minidump and a log file with Dr. Watson. A public=20
test case isn't possible, because we don't have a public cell.
I agree with you, that it make no sense to create such links. But our=20
software developer use scripts for creating links with absolute paths to=20
include and library directories. The results of some scripts are such=20
links with "../.." and "..". I also think, that when such links are=20
possible under Linux, it could also happen by other users.
The limit of 100 characters is really strange, but I did some test with=20
shorter links without problems.
When you have clients to test, I can do an install and check these=20
clients against our environment.
