Merge 18c36b1e24 into c946b13575 2024-11-23 04:04:14 +09:00
Christian Hesse c946b13575 link README.logs from tmpfiles.d/legacy.conf only if available
The file README.logs is installed only if SysVInit support is enabled.
Thus the link should depend on it as well.

Lennart Poettering e412fc5e04 userbdctl: show 'mapped' user range only inside of userns
Outside of userns the concept makes no sense, there cannot be users
mapped from further outside.

basic/cgroup-util: port cg_pidref_get_path() to pidfd_get_cgroupid() 2024-11-19 23:03:19 +01:00

basic/cgroup-util: introduce generic cg_path_from_cgroupid() helper 2024-11-19 23:03:19 +01:00
Mike Yuan bcfcd1e5be
nsresourced: don't specify REMOVE_PHYSICAL, remove redundant safety check
Even without REMOVE_PHYSICAL, rm_rf() permits cgroupfs, hence
just delegate the safety check to that.
