For example, Linux, the kernel, took awhile to mature. The Debian GNU/Hurd system is developing rapidly. Assistance with programming and support tasks is greatly appreciated. The general [Hardware Compatibility Guide](http://www.freesoftware.fsf.org/thug/gnumach_hardware.html) is another good reference. - -Now, the list of known limitations of the Hurd. - -* ~1.5+ GB ext2 partition size limit +* ~1.5 GB ext2 file system size limit * The problem is fixed in the Debian GNU/Hurd distribution but not the official sources, see [this email](http://lists.debian.org/debian-hurd/2007/07/msg00087.html) * See [[ExtTwoSize]] -* Missing device drivers. - * Current GNUMach drivers are from Linux 2.0. - * [[Mach/OskitMach]] currently has Linux 2.2 drivers. +* Many Unsupported Devices. + * See [[Mach/HardwareControlList]] -* Swap is [highly recommended](http://www.gnu.org/software/hurd/faq.en.html#q2-7), like on UNIX systems. - -* Minimum of 8 MB RAM has been reported to work, but 32 MB is more realistic. Don't forget to use plenty of swap space. - -* Random devices, /dev/random and /dev/urandom, are not in the main distribution yet. These are needed by, for instance, OpenSSH. +* Entropy.
