Hello,
Is there a way to use ccache for "guix build" ?

Can't this lead to build problems because to this cache? This is what
other projects say about building with a cache at least.

I would only enable it when packaging new SW, so that rebuilds are faster,
and also would do a final build without to be extra sure...
I used ccache quite a lot, and it saved far more time than it made me loose,
I seem to remember having build glitches sometimes, but nothing significant,
it is very conservative in its "caching" algos...
So I take this has not been used for guix build...

The short answer is “no”, because we cannot inject ccache in the build
process without changing it, strictly speaking. However, the store is
essentially a cache, only coarse-grained compared to that of ccache.
