Many tests depend on that symbolic links work.  This introduces a check
that sets the prerequisite tag SYMLINKS if the file system supports
symbolic links.  Since so many tests have to check for this prerequisite,
we do the check in test-lib.sh, so that we don't need to repeat the test
in many scripts.
To check for 'ln -s' failures, you can use a FAT partition on Linux:
$ mkdosfs -C git-on-fat 1000000
$ sudo mount -o loop,uid=j6t,gid=users,shortname=winnt git-on-fat /mnt
Clone git to /mnt and
$ GIT_SKIP_TESTS='t0001.1[34] t0010 t1301 t403[34] t4129.[47] t5701.7
          t7701.3 t9100 t9101.26 t9119 t9124.[67] t9200.10 t9600.6' \
        make test
(These additionally skipped tests depend on POSIX permissions that FAT on
Linux does not provide.)

test_description='Test the very basics part #1.
 | 
						|
 | 
						|
The rest of the test suite does not check the basic operation of git
 | 
						|
plumbing commands to work very carefully.  Their job is to concentrate
 | 
						|
on tricky features that caused bugs in the past to detect regression.
 | 
						|
 | 
						|
This test runs very basic features, like registering things in cache,
 | 
						|
writing tree, etc.
 | 
						|
 | 
						|
Note that this test *deliberately* hard-codes many expected object
 | 
						|
IDs.  When object ID computation changes, like in the previous case of
 | 
						|
swapping compression and hashing order, the person who is making the
 | 
						|
modification *should* take notice and update the test vectors here.
