Testing Details

The GNU HURD port is built and tested on the following system:

• ESXi Virtual Machine (32-bit)
• 4GB RAM
• GNU polemos 0.9 GNU-Mach 1.8+git20230526-486/Hurd-0.9 i686-AT386 GNU
• gcc 12.2.0-14+hurd.1
• autoconf 2.71
• automake 1.16.5

Required Kernel Tuning

GNU HURD seems to adjust its IPC limits dynamically, as IPC is a user-space subsystem.

Port Challenges

• GNU HURD lacks System V semaphore operations, though shared memory is supported -- we're looking at using fcntl locks as a workaround
• File I/O operations seem to regularly freeze the daemon and raise CPU usage to 85% or higher on the ext2fs process
