I've been using /run, with /var/run as a symlink to that, created in a permanent postinstall script /etc/postinstall/zp_mk_run_var_links.dash (with some others), for some time. It's currently using ~28KB. Is it feasible to mount /run on say /dev/shm/run and create and use files there? Or would it be more feasible to use say Cyg/WinFUSE to provide that function? -- Take care.
