Description Yahel Zamir 2014-06-21 19:43:38 UTC

systemd documentation does not mention clearly what are the field names to replace  bash ulimit command:
·         LimitNOFILE= replaces “ulimit –n”
·         LimitMSGQUEUE= replaces “ulimit –q”
·         LimitCORE= replaces “ulimit –c”

The documentation just mentions the C functions, but systemd replaces mostly initialization shell scripts, therefore its documentation, at least some FAQ or other text, should mention its alternative for useful shell commands.

The same goes for other bash commands, such as "taskset".

Hi,

man page improved for equivalence between Limit* and ulimit: http://cgit.freedesktop.org/systemd/systemd/commit/?id=b8825fff7bf153ea9f17c46a40278df2e780829d

As for taskset/CPUAffinity= the equivalence is straightforward ?
