bug#43132: [GUIX SYSTEM]: Malfunction

[Raghav Gururajan]

Hello Guix!

[1] Out of no where, when I did `guix environment foo`, I got:

\note: build failure may have been caused by lack of free disk space
builder for `/gnu/store/2ajnpcblwpgzjdhx3050qapy3li31pr5-profile.drv'
failed with exit code 1

[2] When I redid the command 2nd time, I got:

error (ignored): cannot unlink `/tmp/guix-build-profile.drv-0':
Read-only file system
error (ignored): cannot unlink
`/gnu/store/2ajnpcblwpgzjdhx3050qapy3li31pr5-profile.drv.chroot/tmp/guix-build-profile.drv-0':
Read-only file system
guix environment: error: cannot link
`/gnu/store/.links/1jd7y4xvj853m4aygnyixci5h2y7a1py6iavp9kwzvcinyniqwbd' to
`/gnu/store/3klrs2bkcmypwnmx61q24rc7csgk19f8-profile/share/icons/Adwaita/64x64/emotes/face-smile-big
symbolic.symbolic.png': Read-only file system

[3] When I redid the command 3rd time, I got:

guix environment: error: fport_read: Connection reset by peer

[4] When I redid the command 4th time, I got:

guix environment: error: failed to connect to
`/var/guix/daemon-socket/socket': Connection refused

[5] So I tried to restart guix-daemon and got a weird output:

sudo: unable to open /var/run/sudo/ts/rg: Read-only file system
Password:
Service guix-daemon is not running.
Service guix-daemon is currently disabled.

[6] Then I tried to enable the daemon:

sudo: unable to open /var/run/sudo/ts/rg: Read-only file system
Password:
Enabled service guix-daemon.

[7] Then I tried to start the daemon:

sudo: unable to open /var/run/sudo/ts/rg: Read-only file system
Password:
Service guix-daemon has been started.

[8] Now, I retried the `guix environment foo` and got same error as in 4.

[9] At this point, all the other running applications started to throw
errors regarding read-only file-system. I could not even save the above
errors in a text editor. Glad that I had the IceCat running and I was
able to email it to myself. IceCat wasn't affected, as I think the
web-process was containerized. Everything was back to normal after restart.

[10] I am experiencing this situation for the 3rd time this month. It
never happened before this month.
