can't read "fpath": no such variable
    while executing
"file tail $fpath"
    (procedure "Exec" line 58)
    invoked from within
"Exec $vm {*}$exe"
    (procedure "prelude" line 15)
    invoked from within
"prelude $vm"
    (procedure "::cluster::init" line 43)
    invoked from within
"cluster init $vm  -steps [cluster steps "worker" $steps]  -masters [Masters $cluster]  -applications [dict get $cluster -applications]  -networks [dic..."

                if { [string match -nocase "swarm*mode" $clustering] } {

    ("reinit" arm line 17)
    invoked from within
"switch -nocase -- $cmd {

    (procedure "::api::cli::command" line 2)
