Hi, Updating the package r-chemminer, it leads to this huge stack of grafts. To be concrete, it is 84 grafts for a “simple” R packages. On my machine, the grafting steps are longer than building (compiling and R dance).
We definitively need a way to tackle this. Maybe when is in frozen state, we could spend 2-5 days to tackle as much as graft that we can. The previous Leo’s initiative is really worth and maybe we should have a hackathon or something because my feeling is that more grafts are added than removed. Cheers, simon --8<---------------cut here---------------start------------->8--- applying 1 graft for /gnu/store/…-dbus-1.12.16.drv ... grafting '/gnu/store/…-dbus-1.12.16' -> '/gnu/store/…-dbus-1.12.16'... successfully built /gnu/store/…-dbus-1.12.16.drv applying 1 graft for /gnu/store/…-cyrus-sasl-2.1.27.drv ... grafting '/gnu/store/…-cyrus-sasl-2.1.27' -> '/gnu/store/…-cyrus-sasl-2.1.27'... successfully built /gnu/store/…-cyrus-sasl-2.1.27.drv applying 1 graft for /gnu/store/…-libxrender-0.9.10.drv ... grafting '/gnu/store/…-libxrender-0.9.10' -> '/gnu/store/…-libxrender-0.9.10'... successfully built /gnu/store/…-libxrender-0.9.10.drv applying 1 graft for /gnu/store/…-libxt-1.2.0.drv ... grafting '/gnu/store/…-libxt-1.2.0' -> '/gnu/store/…-libxt-1.2.0'... successfully built /gnu/store/…-libxt-1.2.0.drv applying 2 grafts for /gnu/store/…-libxft-2.3.3.drv ... grafting '/gnu/store/…-libxft-2.3.3' -> '/gnu/store/…-libxft-2.3.3'... successfully built /gnu/store/…-libxft-2.3.3.drv applying 3 grafts for /gnu/store/…-libxmu-1.1.3.drv ... grafting '/gnu/store/…-libxmu-1.1.3' -> '/gnu/store/…-libxmu-1.1.3'... successfully built /gnu/store/…-libxmu-1.1.3.drv applying 3 grafts for /gnu/store/…-libxpm-3.5.13.drv ... grafting '/gnu/store/…-libxpm-3.5.13' -> '/gnu/store/…-libxpm-3.5.13'... successfully built /gnu/store/…-libxpm-3.5.13.drv applying 2 grafts for /gnu/store/…-openjpeg-2.3.1.drv ... grafting '/gnu/store/…-openjpeg-2.3.1' -> '/gnu/store/…-openjpeg-2.3.1'... successfully built /gnu/store/…-openjpeg-2.3.1.drv applying 5 grafts for /gnu/store/…-libxaw-1.0.13.drv ... grafting '/gnu/store/…-libxaw-1.0.13' -> '/gnu/store/…-libxaw-1.0.13'... successfully built /gnu/store/…-libxaw-1.0.13.drv applying 1 graft for /gnu/store/…-openldap-2.4.57.drv ... grafting '/gnu/store/…-openldap-2.4.57' -> '/gnu/store/…-openldap-2.4.57'... successfully built /gnu/store/…-openldap-2.4.57.drv applying 1 graft for /gnu/store/…-ruby-2.6.5.drv ... grafting '/gnu/store/…-ruby-2.6.5' -> '/gnu/store/…-ruby-2.6.5'... successfully built /gnu/store/…-ruby-2.6.5.drv applying 2 grafts for /gnu/store/…-curl-7.74.0.drv ... grafting '/gnu/store/…-curl-7.74.0' -> '/gnu/store/…-curl-7.74.0'... successfully built /gnu/store/…-curl-7.74.0.drv applying 2 grafts for /gnu/store/…-tk-8.6.10.drv ... grafting '/gnu/store/…-tk-8.6.10' -> '/gnu/store/…-tk-8.6.10'... successfully built /gnu/store/…-tk-8.6.10.drv applying 3 grafts for /gnu/store/…-python-3.8.2.drv ... grafting '/gnu/store/…-python-3.8.2' -> '/gnu/store/…-python-3.8.2'... grafting '/gnu/store/…-python-3.8.2-tk' -> '/gnu/store/…-python-3.8.2-tk'... successfully built /gnu/store/…-python-3.8.2.drv applying 3 grafts for /gnu/store/…-python2-2.7.17.drv ... grafting '/gnu/store/…-python2-2.7.17' -> '/gnu/store/…-python2-2.7.17'... grafting '/gnu/store/…-python2-2.7.17-tk' -> '/gnu/store/…-python2-2.7.17-tk'... successfully built /gnu/store/…-python2-2.7.17.drv applying 2 grafts for /gnu/store/…-glib-2.62.6.drv ... grafting '/gnu/store/…-glib-2.62.6-bin' -> '/gnu/store/…-glib-2.62.6-bin'... grafting '/gnu/store/…-glib-2.62.6' -> '/gnu/store/…-glib-2.62.6'... successfully built /gnu/store/…-glib-2.62.6.drv applying 4 grafts for /gnu/store/…-cairo-1.16.0.drv ... grafting '/gnu/store/…-cairo-1.16.0' -> '/gnu/store/…-cairo-1.16.0'... successfully built /gnu/store/…-cairo-1.16.0.drv applying 4 grafts for /gnu/store/…-cairo-1.16.0.drv ... grafting '/gnu/store/…-cairo-1.16.0' -> '/gnu/store/…-cairo-1.16.0'... successfully built /gnu/store/…-cairo-1.16.0.drv applying 1 graft for /gnu/store/…-harfbuzz-2.6.4.drv ... grafting '/gnu/store/…-harfbuzz-2.6.4' -> '/gnu/store/…-harfbuzz-2.6.4'... successfully built /gnu/store/…-harfbuzz-2.6.4.drv applying 5 grafts for /gnu/store/…-poppler-0.86.1.drv ... grafting '/gnu/store/…-poppler-0.86.1' -> '/gnu/store/…-poppler-0.86.1'... successfully built /gnu/store/…-poppler-0.86.1.drv applying 6 grafts for /gnu/store/…-pango-1.44.7.drv ... grafting '/gnu/store/…-pango-1.44.7' -> '/gnu/store/…-pango-1.44.7'... successfully built /gnu/store/…-pango-1.44.7.drv applying 13 grafts for /gnu/store/…-texlive-bin-20190410.drv ... grafting '/gnu/store/…-texlive-bin-20190410' -> '/gnu/store/…-texlive-bin-20190410'...
