Knot complains about file-descriptors hard limit


on resolver restart, it prints this warning:

Jul  9 09:36:34 omnia kresd[12002]: [system] warning: hard limit for number of file-descriptors is only 4096 but recommended value is 524288

How to properly increase this limit?

This shouldn’t be any problem for SOHO usage. The resolver “is the same” from tiny installations like this up to huge ones, so in this case the log is an unfortunate red herring.
