2d hex is '-', not '/'. The actual reason is that '-' in slice names has
a special meaning to separate hierarchical components, and '-' within
component names is escaped. "system-systemd\x2dfsck.slice" means
subslice "systemd-fsck" of "system" slice, and it's printed that way to
distinguish it from a 3-level hierarchy "system", "systemd", "fsck".
