It does not work when using no-grafts. However, a big ’guix gc’ makes it work. It is really weird. Note that the previous pre-inst-env is done before GC. Well, I have not been enough attentive to correctly save the problematic part. Now, I am unable to reproduce. )-: It is hard to know what had been initially substituted and what had been locally recompiled. I mean, today and after GC, it looks like, --8<---------------cut here---------------start------------->8--- 0,4 MB will be downloaded module-import-compiled 99KiB 597KiB/s 00:00 [##################] 100.0% libfontenc-1.1.4 13KiB 2.3MiB/s 00:00 [##################] 100.0% module-import-compiled 56KiB 601KiB/s 00:00 [##################] 100.0% mkfontscale-1.2.1 20KiB 3.7MiB/s 00:00 [##################] 100.0% module-import-compiled 116KiB 860KiB/s 00:00 [##################] 100.0% mkfontdir-1.0.7 4KiB 3.3MiB/s 00:00 [##################] 100.0% module-import-compiled 9KiB 2.9MiB/s 00:00 [##################] 100.0% module-import-compiled 56KiB 853KiB/s 00:00 [##################] 100.0% module-import-compiled 46KiB 1.1MiB/s 00:00 [##################] 100.0% building /gnu/store/splvvik624s9nyxysz6b1970pq5hy4gp-config.scm.drv... building /gnu/store/w3229vmzf5620pkcn785xfw1ahl3jhri-config.scm.drv... building /gnu/store/lhrdcca79hjjnmhz25bgzmg1a9hc3j7i-guix-config-source.drv... building /gnu/store/i63lwisk345si6552rwyry3pfaa6wqij-guix-core-source.drv... building /gnu/store/hsskiqmzd6822jxqday78kqabi0m3dj6-guix-config.drv... building /gnu/store/dhxdn4wc1rdw13cmy8b20qc23vgvirvc-guix-core.drv...

If these had been substituted and if the substitutes had something incompatible with my hardware for whatever reason, then weird behaviour. Hum, too many if. :-) Cheers, simon
