When a build invoked with --no-build-hook -K --log-file fails, this is the
last output you'll see:

14:01.58 565 compiler warnings present.
mach configuremachphase `configure' failed after 869.5 seconds
note: keeping build directory `/tmp/guix-build-thunderbird-52.2.1.drv-0'
builder for `/gnu/store/n7qma1ypp2px1shd88r736ykjg5dngll-thunderbird-52.2.1.drv' failed with exit code 1
@ build-failed /gnu/store/n7qma1ypp2px1shd88r736ykjg5dngll-thunderbird-52.2.1.drv - 1 builder for `/gnu/store/n7qma1ypp2px1shd88r736ykjg5dngll-thunderbird-52.2.1.drv' failed with exit code 1
guix build: error: build failed: build of `/gnu/store/n7qma1ypp2px1shd88r736ykjg5dngll-thunderbird-52.2.1.drv' failed

As far as I remember from builds I have aborted at the beginning, the
logfile name is displayed when the build process beginns.

In my opinion we should also display them at the end builds (however they end).
If we don't record logs of failed builds, we should start doing that.

On days where I run not so many builds, I can get the name
with ls -al /var/log/guix/drvs/ | grep "Aug 25" (for today)
and then look at the timestamps in the folders I get.
That's not very reliable, so it should be improved.

I don’t think it’s necessary, we can always get the file name with “guix
build --log-file”, can’t we?
