How can I capture the verbose output of an INLA model in R?

Question

Hopefully, this example illustrates what I'm trying to do.

I run a comparison of the same simple example toggling verbose TRUE and FALSE.

library("INLA")
test <- capture.output(
{
inla(speed ~ dist, data = datasets::cars, verbose = F)

    }
    )

I try and capture the verbose output. It appears in my console but is not captured. test and test2 appear identical.

library("INLA")
test2 <- capture.output(
{
inla(speed ~ dist, data = datasets::cars, verbose = T)

    }
    )

I've had the answer to this from [email protected]. If you set verbose = F, default, then the log is stored in a file.

> r=inla(y~1,data=data.frame(y=0))
> head(r$logfile)
[1] "        Read ntt 4 1 with max.threads 8"                          
[2] "        Found num.threads = 4:1 max_threads = 4"                  
[3] "        file: src/inla.c  4f8384f383a924449b14072dec7e4f9ce74ca121
- Wed Feb 16 14:16:16 2022 +0300"            
[4] "Report bugs to <[email protected]>"                                 
[5] "Set reordering to id=[0] and name=[default]"                      
[6] "Process file[/tmp/Rtmpv5S9QO/file1c6414e8a909a/Model.ini]
threads[4] max.threads[8] blas_threads[1] nested[4:1]"

Got to say since the logfile element isn't mentioned in the inla class documentation or in the verbose parameter to the function. I don't feel too bad about not spotting this.
