[arch-releng] regression with race condition on pxe boot with nbd
by Christian Hesse 27 May '16

27 May '16

Hello everybody, with my latest builds I see a regression on pxe boot with nbd. About 50% of boots fail. The nbd module is loaded, nbd-client attaches the device, but mount fails: mount: you must specify the filesystem type ERROR; Failed to mount '/dev/nbd0' Falling back to interactive prompt You can try to fix the problem manually, log out when you are finished A simple mount allows to continue boot: mount /dev/nbd0 /run/archiso/bootmnt/ <Ctrl>-d My guess is that linux 4.6 introduced a race condition. Any idea how to fix or handle this? -- main(a){char*c=/* Schoene Gruesse */"B?IJj;MEH" "CX:;",b;for(a/* Best regards my address: */=0;b=c[a++];) putchar(b-1/(/* Chris cc -ox -xc - && ./x */b/42*2-3)*42);}

[arch-releng] systemctl set-default
by Christian Hesse 27 May '16

27 May '16

Hello everybody, currently things work, but this is a heads-up in case things break. In customize_airootfs.sh we run: systemctl set-default multi-user.target With systemd v230 this is broken. The target is set to be the default, but systemctl returns 1. I've send changes upstream, but the commits have not been merged, yet: https://github.com/systemd/systemd/pull/3336 So we should keep old systemd in [core] until the iso image is built or fix the package in [testing] before move. -- main(a){char*c=/* Schoene Gruesse */"B?IJj;MEH" "CX:;",b;for(a/* Best regards my address: */=0;b=c[a++];) putchar(b-1/(/* Chris cc -ox -xc - && ./x */b/42*2-3)*42);}
