|
Version 0 quota format differs from version 1 by having only 32-bit
|
|
counters for inodes and block limits. For many installations this is not
|
|
limiting and thus the format is widely used. Also quota tools still
|
|
create quota files with this format by default. Add support for this
|
|
quota format to e2fsprogs so that we can seamlessly convert quota files
|
|
in this format into our internal quota files.
