It does take some time, but since I can see the output change from grafting to grafting, I at least can tell guix is doing something, so I just let it be. Compared to grafting, the last step "construyendo perfil con X paquetes..." ("building profile with X packages..."), just stays there without change for several minutes, so it actually seems slower to me. Initially, I thought that guix had frozen. Also, even though, the "building profile" step has a throbber (| / - \) to indicate that something is being done, it frequently stops in one of the frames of the sequence and stays there until the end. > We should hack (guix status) so it can optionally prefix each event with > a timestamp. > > As far as ‘xdg-mime-database’ is concerned, it should be down to 0s, > unless your profile contains one of the packages I cited (libreoffice, > gcr, hugin, etc.). Yes, I have Libreoffice installed.
