Axis Communications is running fairly compact version of systemd with some properties disabled with --disable--xyz. Files are a bit over 10 mb on MIPS ISA (stripped of binaries and conf files).
Top 10 large files are (in kb) 276 ./Root/usr/lib/systemd/systemd-udevd 280 ./Root/usr/bin/udevadm 288 ./Root/usr/bin/busctl 296 ./Root/usr/lib/systemd/systemd-hostnamed 300 ./Root/usr/lib/systemd/systemd-timedated 304 ./Root/usr/lib/systemd/systemd-bus-proxyd 368 ./Root/usr/bin/systemd-nspawn 548 ./Root/usr/bin/systemctl 1152 ./Root/usr/bin/systemd-analyze 1220 ./Root/usr/lib/systemd/systemd Umut [1] Maybe it is time (again) to visit making /shared code part of libsystemd or libsystemd-internal. Has anyone made any calculation regarding the cost of using static library. If not, maybe I can take a stab. [2] I am quite surprised systemd-analyze is so big. On 18 Sep 2014, at 05:19 pm, Jóhann B.
