Package: schroot Version: 1.6.10-11+b1 Severity: normal -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256

This breaks a common strategy (used e.g. by slurm) for sharing multi-processor machines. ╭─ simplex:~ ╰─% grep Cpus_allowed_list /proc/self/status Cpus_allowed_list: 0,2,4,6,8,10,12,14,16,18,40,42,44,46,48,50,52,54,56,58 ╭─ simplex:~ ╰─% schroot -c sid grep Cpus_allowed_list /proc/self/status Cpus_allowed_list: 0-79 - -- System Information: Debian Release: bullseye/sid APT prefers unstable-debug APT policy: (500, 'unstable-debug'), (500, 'testing-debug'), (500, 'testing') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 5.10.0-1-amd64 (SMP w/8 CPU threads) Kernel taint flags: TAINT_OOT_MODULE, TAINT_UNSIGNED_MODULE Locale: LANG=en_CA.UTF-8, LC_CTYPE=en_CA.UTF-8 (charmap=UTF-8), LANGUAGE=en_CA:en Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages schroot depends on: ii libboost-filesystem1.74.0 1.74.0-8 ii libboost-iostreams1.74.0 1.74.0-8 ii libboost-program-options1.74.0 1.74.0-8 ii libc6 2.31-9 ii libgcc-s1 10.2.1-6 ii libpam0g 1.4.0-2 ii libstdc++6 10.2.1-6 ii libuuid1 2.36.1-6 ii lsb-base 11.1.0 ii schroot-common 1.6.10-11 schroot recommends no packages.
