-----Original Message----- From: Clemens Gruber [mailto:clemens.gru...@pqgruber.com] Sent: Thursday, May 19, 2016 10:06 AM To: ptxdist@pengutronix.de Cc: Clemens Gruber Subject: [ptxdist] [PATCH] systemd: add setting to enable ldconfig service Add a ptxdist setting to enable the systemd ldconfig.service, which calls /sbin/ldconfig -X if /etc/ld.so.cache does not exist and the machine boots or was updated. Having a /etc/ld.so.cache file reduces the number of necessary syscalls dramatically. This is especially noticeable when often calling small binaries like /bin/true.
