biod has been blamed on some swap space fragmentation. This patch will
reduce size:
% size biod /etc/biod
text data bss dec hex
4096 2048 0 6144 1800 biod
18432 4096 0 22528 5800 /etc/biod
The interesting change is to remove "printf" and print "biod" instead of
argv[0] (given the normal usage of biod, I do not think this is a problem).
Also, <sys/errno.h> is included (since errno is referenced) and "biod 0" is
an error.
