Subject: core: Add RootDirectoryFileDescriptor= (#39480)
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=dd15dd1a586ceed5e6b9bc6324227c09d7d4480e;p=thirdparty%2Fsystemd.git

core: Add RootDirectoryFileDescriptor= (#39480)

RootDirectory= but via a open_tree() file descriptor. This allows
setting up the execution environment for a service by the client in a
mount namespace and then starting a transient unit in that execution
environment using the new property.

We also add --root-directory= and --same-root-dir= to systemd-run to
have it run services within the given root directory. As systemd-run
might be invoked from a different mount namespace than what systemd is
running in, systemd-run opens the given path with open_tree() and then
sends it to systemd using the new RootDirectoryFileDescriptor= property.
