Hi, Using Guix 6113e05, I notice a behaviour that I do not expect.
--8<---------------cut here---------------start------------->8--- $ guix shell xterm --dry-run The following derivation would be built: /gnu/store/x26rsb69l3jjxczx2ap0i3app6q8prwl-profile.drv $ which xterm /usr/bin/xterm $ guix shell xterm The following derivation will be built: /gnu/store/x26rsb69l3jjxczx2ap0i3app6q8prwl-profile.drv building CA certificate bundle... listing Emacs sub-directories... building fonts directory... building directory of Info manuals... building profile with 1 package... $ which xterm /gnu/store/9phsgk6m6h7gy09698m5a0s42aqi9yid-profile/bin/xterm --8<---------------cut here---------------end--------------->8--- So far, so good. Now, even if --dry-run is provided, it enters the profile. --8<---------------cut here---------------start------------->8--- $ which xterm /usr/bin/xterm $ guix shell xterm --dry-run $ which xterm /gnu/store/9phsgk6m6h7gy09698m5a0s42aqi9yid-profile/bin/xterm --8<---------------cut here---------------end--------------->8--- Well, I thought maybe that’s because --rebuild-cache, but no: --8<---------------cut here---------------start------------->8--- $ which xterm /usr/bin/xterm $ guix shell xterm --dry-run --rebuild-cache $ which xterm /gnu/store/9phsgk6m6h7gy09698m5a0s42aqi9yid-profile/bin/xterm --8<---------------cut here---------------end--------------->8--- Well, and I thought that --rebuild-cache redoes the dance: --8<---------------cut here---------------start------------->8--- building CA certificate bundle... listing Emacs sub-directories... building fonts directory... building directory of Info manuals... building profile with 1 package... --8<---------------cut here---------------end--------------->8--- and not, if I do not miss something.
