I am convincing some powers-that-be that having a build farm would

There is a bunch of somewhat old Linux workstations that could
contribute to it. The concern is mostly that it should be so that the
systems should not accept jobs when users are logged in, as it may
interfere with whatever work it is that they are doing.
Maybe more interesting than "nobody logged on" would be "system load
very low", e.g. "load <= 0.1*(number of cores)", possibly combined
with "free memory + memory used for cache >= threshold".
I'm sure they'd accept a patch to add a config option to use some
system heuristic before accepting a job. Of course, reliably detecting
a
login session is prolly quite fun in itself ;-) ps ax | grep
gnome-session | kdeinit or something ?
Nah:
#include <utmpx.h>
struct utmpx *getutxent(void);
struct utmpx *getutxid(const struct utmpx *);
struct utmpx *getutxline(const struct utmpx *);
struct utmpx *pututxline(const struct utmpx *);
void setutxent(void);
void endutxent(void);
is the POSIX/SUS interface to do that. Or just run "/usr/bin/who -q"
:)
