FSCK MESSAGES
|
||||
-------------
|
||||
|
||||
The following lists the types of errors `git fsck` detects and what
|
||||
each error means, with their default severity. The severity of the
|
||||
error, other than those that are marked as "(FATAL)", can be tweaked
|
||||
by setting the corresponding `fsck.<msg-id>` configuration variable.
