Hi there,
After getting libacl to compile on GNU/Hurd, i got stumbled on runtime
problems [1]. It seems to be using kernel-specific interfaces that need to
be implemented in Glibc/Hurd.
Below is a mail from libacl upstream describing the implementation of EA/ACL
interfaces on other operating systems. Just in case someone wants to hack on
this..
[1] "Illegal instruction". Probably the result of attempting to access
syscalls via interrupts. I didn't have GDB at hand to check, though.
