- Fix for possible unset uid/gid in toproto
- Fix for default mtree style
- Update libelf
- Importing libexecinfo
- Resynchronize GCC, mpc, gmp, mpfr
- build.sh: Replace params with show-params.
This has been done as the make target has been renamed in the same
way, while a new target named params has been added. This new
target generates a file containing all the parameters, instead of
printing it on the console.
- Update test48 with new etc/services (Fix by Ben Gras <ben@minix3.org)
get getservbyport() out of the inner loop

.Sh DESCRIPTION
|
|
.Nm
|
|
is a reimplementation of the file system in user space subsystem.
|
|
Operations are transported from the kernel virtual file system layer
|
|
to the concrete implementation behind
|
|
.Nm ,
|
|
where they are processed and results are sent back to the kernel.
|
|
.Pp
|
|
It uses the framework provided by the
|
|
.Xr puffs 3
|
|
subsystem, and, through that, the kernel interface provided by
|
|
.Xr puffs 4 .
