entry won't be the same as that found in Root Filename, but instead reflects
the newly compressed file. This change was precipitated by the previous
change to the Accept behavior.
the uml_exclusively and genext2fs behavior are handled by Create, this is
much nicer because a new filsystem type can be created without having to wait
for everything to be copied again to the sources directory.
If a terminfo directory is found, linux will need to exist or the test will
return error. This is better because the root filesystem can still work
if this information doesn't exist. A minority of gettys will fail if they
use termcap or terminfo, but this check was removed from the chrooted tests
several months ago for the reason just cited. Note: check_getty_type_call
was removed from Yard.pm, but exists in chrooted tests without the termcap
check. Also, added a close which was missing.
