.TH qmail-newu 8 .SH NAME qmail-newu \- prepare address assignments for qmail-lspawn .SH SYNOPSIS .B qmail-newu .SH DESCRIPTION .B qmail-newu reads the assignments in .B /var/lib/qmail/users/assign and writes them into .B /var/lib/qmail/users/cdb in a binary format suited for quick access by .BR qmail-lspawn . If there is a problem with .BR users/assign , .B qmail-newu complains and leaves .B users/cdb alone. .B qmail-newu ensures that .B users/cdb is updated atomically, so .B qmail-lspawn never has to wait for .B qmail-newu to finish. However, .B qmail-newu makes no attempt to protect against two simultaneous updates of .BR users/cdb . The binary .B users/cdb format is portable across machines. .SH "SEE ALSO" qmail-users(5), qmail-lspawn(8), qmail-pw2u(8)
