It looks like the otpclient package could change the default maximum memlock for all users by installing a config file in /etc/systemd/ user.conf.d.
There are two memlock values, one for root and one for other users. The current value for root can be read from /proc/1/limits. On my system it is: Limit Soft Limit Hard Limit Units Max locked memory 8109957120 8109957120 bytes The current value for a non-root user can be read from /proc/2/limits. On my system it is: Limit Soft Limit Hard Limit Units Max locked memory 8388608 8388608 bytes The values for these can be changed in the files /etc/systemd/ system.conf and /etc/systemd/user.conf and in the directories /etc/ systemd/system.conf.d and /etc/systemd/user.conf.d. [Manager] #DefaultLimitMEMLOCK=8M This would change the value for all users on the system. Although as mentioned in the following bug report, there is probably no difficulty in doing so, it might be worth asking the systemd maintainer if they think there would be an issue with an override. https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1103856 For the sake of completeness, this value is set by the Linux kernel, can be reset by systemd, and can also be overwritten by pam for particular groups using /etc/security/limits.conf, which is shipped in libpam-modules. In the past, pam used to override this value by default, but recently stopped doing so. -- Soren Stoutner so...@debian.org
