|This is what happens (no ktraces included):
|
|When the files (version and cpuinfo) are not present, lstat fails and xslite4
|aborts. When the files are present lstat succeeds, but xslite4 fails because
|the files have length > 0 (on Red Hat they have length 0; on FreeBSD they are
|regular files). As a result xslite4 aborts. When you create empty files,
|lstat succeeds and xslite4 will open the files and read them, but will fail
|because it does read what it expects and aborts; after which I aborted :-)
|
|XessLite4 will only run when /proc is properly emulated.
|Sorry,
Thanks for the explanation. I didn't get as much as you did from the
ktrace output.
Don't suppose there is some FreeBSD feature with which one could emulate
this behavior? Maybe a socket or named pipe with a daemon sleeping on the
other end?
