Details:
The string type used by the Hurd in RPCs is limited to 1024 bytes.
This is because it is defined as the MIG type c_string[1024]. That is, it is
stored in an 1024 char array.
The solution would be to declare it unbounded, i.e. c_string[].
Unfortunately, MIG doesn't support unbounded strings like it does
for other arrays.
Effectively this leads to the Hurd having a PATH_MAX=1024, which
can be triggered like so:
p=$(for (( i=0; i < 64; i++ )); do echo -n 123456789abcdef/; done;)
mkdir -p $p
ls $p
