So this likely depends on the setup. 1582559129 M * Guy- AlexanderS: maybe your guest has the host's real /proc? 1582559182 M * Guy- anyway, this /proc/1/sched hack is what eudev from Devuan now uses to avoid starting in a container 1582559236 M * Guy- I think it's wrong for them to try to avoid this (the user should have the option of shooting themselves in the foot), so I won't complain about setups where it fails to detect a container :) 1582559263 M * Guy- I had a problem with their previous approach that mis-detected my runit-using hosts as being containers 1582560496 N * Bertl_zZ Bertl 1582560498 M * Bertl morning folks! 1582560527 M * Bertl Guy-: I'd be interested in the kernel stack trace of the null pointer dereference 1582560553 M * Bertl also, will look at the conflict a little later ... 1582564345 Q * hijacker 1582569632 J * fstd_ ~fstd@xdsl-87-79-157-139.nc.de 1582570098 Q * fstd Ping timeout: 480 seconds 1582572457 J * Aiken ~Aiken@b951.h.jbmb.net 1582577123 Q * Guy- Quit: malenkiy reboot 1582579154 M * Bertl off for now ... bbl 1582579155 N * Bertl Bertl_oO 1582579365 Q * Ghislain 1582580963 J * Guy- ~korn@0002809d.user.oftc.net
