elaborate transactional dependency-based service control logic.
It can work as a drop-in replacement for sysvinit.
Systemd requires a Linux kernel >= 3.0, with inotify, devtmpfs,
tmpfs vfs and tmpfs POSIX ACL enabled.
Systemd requires a Linux kernel >= 3.0 with the following options
enabled:
- CONFIG_CGROUPS
- CONFIG_INOTIFY_USER
- CONFIG_FHANDLE
- 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.
