Subject: Re: Nginx service fails
Date: Mon, 5 Mar 2018 00:06:37 +0100

Well, I am turning this into a bug report, since it still occurs with
the latest git commit ac1a9ce8b07f3b80900ee08436ff6e683e8dc195 .

This is the result of "./pre-inst-env guix system reconfigure ...",
where "..." is my configuration file:

...
creating nginx log directory '/var/log/nginx'
creating nginx run directory '/var/run/nginx'
creating nginx temp directories '/var/run/nginx/{client_body,proxy,fastcgi,uwsgi,scgi}_temp'
nginx: [alert] could not open error log file: open() "/gnu/store/pp71iff1qxwhh82vm34g18h9kmn0xrg5-nginx-1.13.9/logs/error.log" failed (2: No such file or directory)

guix system: error: failed to install bootloader /gnu/store/9iv63jm07klxvrr4fpwv6q5vpnca13ja-bootloader-installer

The final error is "normal", since I am installing in a Xen virtual machine,
where /dev/sda does not exist; it did not matter before.
The real error occurs above, the "uncaught exception".

But:
# herd status nginx
herd: service 'nginx' could not be found

Then I do a
# ./pre-inst-env guix system roll-back
# herd status nginx
herd: service 'nginx' could not be found

Otherwise said, I can go back, but my previously running web server has
definitely gone! How do I get it back?

Andreas
