cwfs(4) tips ============ No-dump configuration --------------------- A cheap VPS or an SD card lack the storage capacity for running a usable default `cwfs(4)` setup with a big WORM partition and daily dumps. The go-to solution is the `hjfs(4)` file system, which doesn't use a dedicated WORM partition and doesn't do daily dumps by default. However, it has several performance problems and is not as well tested. The `cwfs` file system can be configured in lots of ways beyond the default cache-worm + other configuration supported by the 9front installer. The desired configuration we're going to cover is a single `main` file server tree backed by a simple disk file system - the same type used by the `other` tree in the default setup. To do this we're going to partition the disk appropriately and override the `mountcwfs` stage of the 9front installer with a replacement [script](http://a-b.xyz/23/666a) that will configure `cwfs` appropriately. The rest of the installation and most of the subsequent system operation remain unaffected. Start by booting from the installation media. Configure networking with `ip/ipconfig(8)` and fetch the replacement `mountcwfs` script, or put the script on a flash drive: webfs ramfs hget http://a-b.xyz/23/666a >/tmp/mountcwfs chmod +x /tmp/mountcwfs Override the `mountcwfs` stage using `bind(1)`: bind /tmp/mountcwfs /bin/inst/mountcwfs Run `inst/start` and complete the stages up to `preppart` as you would normally. At `preppart`, delete the default partitions and create one named `fsmain` with a desired size: d other d fscache d fsworm a fsmain 123456 .+100% w q Make sure to "ream" the new partition at the next step. Complete the rest of the installation, reboot. That is all.
