This filesystem is written in the Limbo programming language for the Inferno operating system.
The purgatorio fork of Inferno is recommended.
No other dependencies are required if Inferno is installed.
mk
mk demo
usage: simplefs [-D]
-D enables debug logging and tracing via styx(2).
-u specifies to run the server as owned by user.
Commands are written to the /ctl file in the fs.
/ctl -- command input file
/log -- log of commands written thus far
If you're used to how Plan 9 provides file servers as per postmountsrv(2) and friends, the operation of Inferno file servers may be unintuitive.
In Inferno, a styx(2) file server listens on stdin and if run from the shell directly, will seem to just hang. There are several approaches to making the server accessible, in this case, we use mount(1) to place our file server in an intuitive location.
From inside Inferno:
; mount {mntgen} /n # Not necessary under purgatorio
; mount {simplefs} /n/s
; ls -sl /n/s
