IMO, the expansion of *.log cannot exceed ARG_MAX limitations since for .. in is shell syntax, so there is no new process to which arguments need to be passed..

luseradd(1)						      General Commands Manual						       luseradd(1)

NAME
luseradd - Add an user SYNOPSIS
luseradd [OPTION]... user DESCRIPTION
Adds an user with name user. OPTIONS
-c, --gecos=gecos Set the GECOS field to gecos. The GECOS field is traditionally used to store user's real name and other information. -d, --directory=directory Set user's home directory to directory. If this option is not present, a default specified by libuser configuration is used. -g, --gid=group Set user's primary group to group. group can either be a group ID of an existing group, or a group name; if group is a group name and the group does not exist, it is created. If the --gid option is not specified, the default group name is user. -i, --interactive Ask all questions when connecting to the user database, even if default answers are set up in libuser configuration. -k, --skeleton=directory Populate the newly created user's home directory with a copy of directory. If this option is not present, a default directory spec- ified by libuser configuration, or /etc/skel if libuser configuration does not specify a default, is used. -M, --nocreatehome Don't create a home directory and a mail spool for the newly created user. -n, --nocreategroup If a group is not specified using -g, use group name "users" instead of user. Note that despite the name of the option, the group will still be created if it does not exist. -P, --plainpassword=password Set user's password to password. Note that the password can be viewed while running luseradd using tools such as ps(1). -p, --password=encrypted Set user's password to the password represented by the hash encrypted. Note that the hash can be viewed while running luseradd using tools such as ps(1). -r, --reserved The user is a system user. Users that are not marked as system user usually have automatically selected user IDs above a certain value (configured as LU_UIDNUMBER in libuser.conf(5)). This information is also passed to the libuser backends. This option implies the -M option. -s, --shell=shell Set user's login shell to shell. If this option is not present, a default specified by libuser configuration is used. -u, --uid=uid Use user ID uid for the newly created user. An user ID is selected automatically if this option is not present. --commonname=name Use common name name for the newly created user. This attribute is only supported in some backends (e.g.LDAP), and its support may have further limitations (e.g. LDAP schema rules). --givenname=name Use given name name for the newly created user. This attribute is only supported in some backends (e.g.LDAP), and its support may have further limitations (e.g. LDAP schema rules). --homephone=phone Use home telephone number phone for the newly created user. This attribute is only supported in some backends (e.g.LDAP), and its support may have further limitations (e.g. LDAP schema rules). --roomnumber=room Use room number room for the newly created user. This attribute is only supported in some backends (e.g.LDAP), and its support may have further limitations (e.g. LDAP schema rules). --surname=name Use surname name for the newly created user. This attribute is only supported in some backends (e.g.LDAP), and its support may have further limitations (e.g. LDAP schema rules). --telephonenumber=phone Use telephone number phone for the newly created user. This attribute is only supported in some backends (e.g.LDAP), and its sup- port may have further limitations (e.g. LDAP schema rules). EXIT STATUS
The exit status is 0 on success, nonzero on error. libuser 2009-12-09 luseradd(1)
