- ensure hostname from gethostname() is nul-terminated in all cases
- minor KNF
- use MAXHOSTNAMELEN over various other values/defines
- be safe will buffers that hold hostnames
it to "."
- include sockio.h if needed to define SIOCGIFCONF (for svr4)
- use POSIX signals and wait macros
- add -S silent flag, so that the client does not print messages unless there
is something wrong
- use flock or lockf as appropriate
- use fstatfs or fstatvfs to find out if a filesystem is mounted over nfs,
don't depend on the major() = 255 hack; it only works on legacy systems.
- use gzip -cf to make sure that gzip compresses the file even when the file
would expand.
- punt on defining vsnprintf if _IOSTRG is not defined; use sprintf...
To compile sup on systems other than NetBSD, you'll need a copy of daemon.c,
vis.c, vis.h and sys/cdefs.h. Maybe we should keep those in the distribution?
