spotread doesn't seem to store anything in the CWD for me, and looking
at strace it seems to try to store the value in
/usr/bin/.mk_2023111.cal -- which for a user obviously won't work (and
argyll seems to ignore EACCES without a warning). By bodging PATH and
arg[0] to something more reasonable I could probably get the
calibration file to be saved somewhere else, although this is a giant
hack and probably not a good idea.


$ spotread
gettimeofday({1272450817, 492375}, NULL) = 0
-1, 0) = 0xb6d3a000
munmap(0xb6d3a000, 245760)              = 0
time(NULL)                              = 1272450817
open("/usr/bin/.mk_2023111.cal", O_WRONLY|O_CREAT|O_TRUNC, 0666) = -1
EACCES (Permission denied)
write(1, "Calibration complete\n", 21Calibration complete
)  = 21
write(1, "\nPlace instrument on spot to be "..., 42
Place instrument on spot to be measured,
) = 42
