+Just like any 32bit OS without bad tricks, GNU Mach does not cope well with lots
+of memory.  Newer versions of the Debian `gnumach` package will limit themselves
+to around 1 GiB of memory. If you want more, you can twiddle the VM_MAX_ADDRESS
+limit between kernelland and userland in i386/include/mach/i386/vm_param.h.

 In order to [[debug|debugging]] translators and being able to step into glibc
-during it, you need the `hurd-dbg` and `libc0.3-dbg` packages installed.  Then
+during it, you need the `hurd-dbg` and `libc0.3-dbg` packages installed.  If you need to debug the initialization of the translator,
 start the translator like `settrans -P /foo /usr/bin/env
 LD\_LIBRARY\_PATH=/usr/lib/debug /hurd/foofs`. The `-P` option will make it
 pause and you will be able to attach [[debugging/GDB]] to the process.
