Key limits: - RLIMIT_FSIZE (file size): 256KiB - RLIMIT_NPROC (after uid changes to a unique uid) Probably unnecessary limits but why not: - RLIMIT_CORE: 0 - RLIMIT_MSGQUEUE: 0 - RLIMIT_LOCKS: 0 - RLIMIT_MEMLOCK: 0 NB that we do not yet set RLIMIT_AS (total virtual memory) or RLIMIT_NOFILES (number of open files), since these require more care and/or more coordination with QEMU to implement.
