There are three "System V compatibility" options in the FreeBSD kernel:
- SYSVSHM implements the System V shared memory facility,
- SYSVSEM implements the System V semaphore facility, and
- SYSVMSG implements the System V message queue facility.
You can enable these by including the following lines in your kernel:
options SYSVSHM
options SYSVSEM
options SYSVMSG
and rebuilding. Check the /usr/src/sys/i386/conf/LINT file for explanations of
other options;
there are *many* options not included in the generic kernel.
