Hi,
adduser does:
if (mkdir(pw.pw_dir, 0755)
|| chown(pw.pw_dir, pw.pw_uid, pw.pw_gid)
|| chmod(pw.pw_dir, 02755) /* set setgid bit on homedir */
) {
bb_simple_perror_msg(pw.pw_dir);
}
so i suspect that chown and/or chmod fail on fat as this operations
are not supported on that filesystem.
Ciao,
TIto
