Hi
Today I booted up my pc from standby.
Qemu was running GuixSD from a cow on an USB-disk.
It had remounted ro and I got weird errors from guix when trying to build.
All other programs just stated the obvious:
"Cannot write to bla bla - read-only filesystem."
Guix of course tried to do a lot but failed of course.
--
Could we add a simple check to the commands that rely on writing to the
filesystem?

Cheers Swedebugia

Could you paste the exact command you run and its output?
TIA,

I did not succede in reproducing. This time I suspended my pc multiple
times but qemu/the kernel did not remount / ro.
So I janked the usb out and back in and that did the trick if I ran a
complicated command while it was out (guix build did the trick) :D
sdb@komputilo ~$ mount
none on /proc type proc (rw,relatime)
none on /dev type devtmpfs
(rw,relatime,size=1002304k,nr_inodes=250576,mode=755)
none on /sys type sysfs (rw,relatime)
/dev/sda1 on / type ext4 (ro,relatime)
none on /dev/pts type devpts (rw,relatime,gid=996,mode=620,ptmxmode=000)
tmpfs on /dev/shm type tmpfs (rw,nosuid,nodev,relatime)
/dev/sda1 on /gnu/store type ext4 (ro,relatime)
sdb@komputilo ~$ guix --version
guix (GNU Guix) 1f44934fb6e2cefccbecd4fa347025349fa9ff76
Unfortunately it errored nicely this time:
sdb@komputilo ~/guix-tree [env]$ ./pre-inst-env guix build hello -K
--substitute-urls="http://berlin.guixsd.org http://mirror.hydra.gnu.org"
guix build: error: fport_read: Connection reset by peer
Then the ssh terminal freezes. (qemu window shows a nice "kernel panic -
not syncing: Attempted to kill init!" :)
Closed the bug.
