Wiping /tmp?

Wiping /tmp?

[Christopher Lemmer Webber]

I'm sure there's something obvious, but what does one put in one's guix
config so that /tmp is wiped by default on reboot?

Maybe not exactly what you want, but you can mount /tmp as tmpfs in memory:

--8<---------------cut here---------------start------------->8---
(file-systems (cons* ...
                         (file-system
                           (mount-point "/tmp")
                           (device "none")
                           (type "tmpfs")
                           (check? #f))
                         %base-file-systems))
--8<---------------cut here---------------end--------------->8---

There used to be a bug where it doesn't get wiped. Or was the workaround/fix
for this to simply not do it anymore?

You could try and see how much of /etc/rc.d/cleartmp of NetBSD is applicable
for you in a small shepherd service:

http://cvsweb.netbsd.org/bsdweb.cgi/src/etc/rc.d/cleartmp?rev=1.13&content-type=text/x-cvsweb-markup&only_with_tag=MAIN

By which I mean, see how early or how late you could run an equivalent
chain of commands. This is what I would try when I'd setup GuixSD
again somewhere.

Hope it helps to some extent.

This is done by the “cleanup-service-type”.

Huhm!  It looks like this is already done by default in
operating-system-default-essential-services.  I guess I don't have to do
anything.

I wonder why I didn't see it wipe things before.  I guess I'll try and
see if it wipes things next time.
