*** Please type your report below this line ***

xfs_quota interprets usernames with leading digits as a numeric UID so,
for example:

# xfs_quota -c 'quota -h -u 2000ad' /store
Disk quotas for User test (2000)
Filesystem   Blocks  Quota  Limit Warn/Time    Mounted on
/dev/sdb1       12K     1G     1G  00 [------] /store

This is returning quota information for the user "test" (UID 2000), rather
than the user "2000ad".


I don't think this is a bug, username must begin with a character (unless you created the user using NIS or adduser --force-badname).

# Default from /etc/adduser.conf
# check user and group names also against this regular expression.
#NAME_REGEX="^[a-z][-a-z0-9_]*\$"

From adduser man page:

      --force-badname
By default, user and group names are checked against the configâ urable regular expression NAME_REGEX (or NAME_REGEX_SYSTEM if --system is specified) specified in the configuration file. This option forces adduser and addgroup to apply only a weak check
              for validity of the name.

Thanks
