Faster boot time isn’t Introduction. systemd can already offer boot times of < 1s for the Core OS (userspace only, i.e. (As a temporary hack it is possible to increase /proc/sys/net/unix/max_dgram_qlen globally, but this has implications beyond systemd, and should probably be avoided.) oder gibt es eie andere lösung? Also remove all LVM/RAID/FCOE/iSCSI related packages which slow down the boot substantially even if no storage of the specific kind is used (and if these RPMs can't be removed because some important packages require them, at least mask the respective services). For example, on Fedora it's a good idea to mask fedora-autoswap.service fedora-configure.service fedora-loadmodules.service fedora-readonly.service. As of Wheezy, the bootlogd package is automatically started as a daemon in the normal way (with a sys-V like init.d script). 3.1 Measurement Method.
