NAME
projects - persistent project root definition
DESCRIPTION
The /etc/projects file provides a mapping between numeric project identifiers and those directories which
are the roots of the quota tree. Its format is simply:
# comments are hash-prefixed
# ...
10:/export/cage
42:/var/log
The /etc/projects file is optional, instead xfs_quota(8) can be used with the -p argument to specify a
project root directly for each operation.
