|
||
systemd is a system and service manager for Linux,
|
||
compatible with SysV and LSB init scripts. systemd provides
|
||
aggressive parallelization capabilities, uses socket and
|
||
D-Bus activation for starting services, offers on-demand
|
||
starting of daemons, keeps track of processes using Linux
|
||
cgroups, supports snapshotting and restoring of the system
|
||
state, maintains mount and automount points and implements
|
||
an elaborate transactional dependency-based service control
|
||
logic. It can work as a drop-in replacement for sysvinit.
|
||
|
||
Kernel versions below 4.15 ("recommended baseline") have
|
||
significant gaps in functionality and are not recommended
|
||
for use with this version of systemd.
|
||
|
||
Systemd requires a Linux kernel >= 3.15 with the following
|
||
options enabled:
|
||
|
||
- CONFIG_DEVTMPFS
|
||
- CONFIG_CGROUPS (it is OK to disable all controllers)
|
||
- CONFIG_INOTIFY_USER
|
||
- CONFIG_SIGNALFD
|
||
- CONFIG_TIMERFD
|
||
- CONFIG_EPOLL
|
||
- CONFIG_UNIX (it requires CONFIG_NET, but every other flag in
|
||
it is not necessary)
|
||
- CONFIG_SYSFS
|
||
- CONFIG_PROC_FS
|
||
- CONFIG_FHANDLE (libudev, mount and bind mount handling)
|
||
|
||
- CONFIG_NET_NS (Required for PrivateNetwork=, used in some
|
||
systemd units)
|
||
|
||
- CONFIG_USER_NS (Required for PrivateUsers=)
|
||
|
||
- CONFIG_AUTOFS_FS / CONFIG_AUTOFS4_FS
|
||
- CONFIG_TMPFS_POSIX_ACL
|
||
- CONFIG_TMPFS_XATTR
|
||
|
||
These options will be automatically enabled by Buildroot if
|
||
it is responsible for building the kernel. Otherwise, if you
|
||
are building your kernel outside of Buildroot, make sure
|
||
these options are enabled.
|
||
|
||
Systemd also provides udev, the userspace device daemon.
|
||
|
||
The selection of other packages will enable some features:
|
||
|
||
- acl package will add support for multi-seat.
|
||
- xz and/or l4 packages will add compression support in
|
||
journal and coredump.
|
||
- libcurl package will add support for systemd-journal-upload.
|
||
- libgcrypt package will add support for journal sealing and
|
||
DNSSEC verification in resolved.
|
||
|
||
Notice that systemd selects the fsck wrapper from util-linux
|
||
but no particular fsck.<fstype> is selected. You must choose
|
||
the apropriate ones (e.g. e2fsck, from the e2fsprogs
|
||
package) according to the system configuration.

systemd-boot does this out of the box.

Utmp keeps track of what users do on the system (where they

logged from, on which terminal, ...) along with a general

status of the system (list of reboots, current uptime, current

number of users logged in).

You should only enable this if your system will have actual

users who log in.
