mdmfs(8) lacks the ability to populate throwaway memory filesystems from an existing directory. This features permits an interesting setup where /var for instance lives on a device where wear-leveling is something you want to avoid as much as possible and nonetheless you don't want to lose your logs, ports metadata, etc. Here are the steps: 1. Copy /var to /var.bak; 2. Mount an mfs into /var using -k /var.bak at startup; 3. Synchronize /var to /var.bak weekly and on shutdown. Note that this more or less mimics OpenBSD's mount_mfs(8) -P flag. PR: 146254 Submitted by: jlh (many moons ago) MFC after: 1 week |
