      1 These images contain various forms of corrupted filesystem which
      2 e2fsck will correct.  They are used as a regression test for e2fsck.
      3 
      4 The test_script program will automatically run e2fsck against the
      5 filesystem images.  It will run them two times, and display the exit
      6 status for each run.  The meaning of the exit status codes are as
      7 follows:
      8 
      9 	0		No filesystem errors were detected
     10 	1		Filesystem errors detected, but corrected
     11 	2		System should be rebooted
     12 	4		Filesystem errors left uncorrected
     13 	8		Operational error (generally means internal error,
     14 				or filesystem error that the e2fsck was not
     15 				prepared to deal with)
     16 	16		Usage or syntax error
     17 
     18 During the regression test, the first exit code should be 1, and the
     19 second exit code should be 0.  In other words, all (with one
     20 exception) of the test filesystems in this directory have some sort of
     21 filesystem corruption, which e2fsck should fix on the first pass.
     22 After the first pass, e2fsck should leave a fully consistent
     23 filesystem with no detectable errors found in the second pass.  The
     24 exception is the okgroup.img filesystem, which contains no errors, and
     25 so both exit codes should be 0.
     26 
     27 NOTE: It appears that at least some versions of the original e2fsck do
     28 not exit with an exit status code of 1 after correcting filesystem
     29 errors.  So if you modify the test_script to try running these
     30 filesystems against the original e2fsck, you will have to inspect the
     31 test_script.log file manually.
