hello Guix, context 1:
i want to write a string into a file at boot to disable wake-up by my keyboard (so that it doesn't immediately wake up my laptop after i suspend it). it requires doing this once per boot: echo XHC >/proc/acpi/wakeup the standard solution on systemd distros is to use a /etc/tmpfiles.d/disable-usb-wake.conf file, which systemd interprets (see e.g. https://forums.linuxmint.com/viewtopic.php?f=42&t=312953). context 2: i need to create an empty directory in an image created by `guix system vm ...` (for "reasons"; this is the simplest way i'm aware of to hack forward). in Guix we have extra-special-file (what a strange name!) that in fact can do one thing: a (single shot?) shepherd service that can symlink something somewhere. what i need is something like extra-special-file, but with a few more keyword arguments that would allow creating empty directories, and appending/overwriting files with content given as literals. or something else that i'm not aware of? solution 1: i think i could backwards compatibly extend extra-special-file with the keyword args. solution 2: introduce a new abstraction (preferrably with a better name), and mark extra-special-file obsolete. dear maintainers, any thoughts on which way i should start digging? also, any suggestion for the API? the naming of the keyword args? -- • attila lendvai • PGP: 963F 5D5F 45C7 DFCD 0A39 -- “Angry people want you to see how powerful they are… loving people want you to see how powerful You are.” — Chief Red Eagle
