That's a bit

? It's not hack, it's how it's

Ah, that's a helpful pointer. What I notice is that Shengyu's last
message says "not merged yet", to which Richard Braun responds
Hello,
Did you have a look at Shengyu Zhang's work on xattr? That's about
summer 2016. Also see glibc/sysdeps/mach/hurd/setxattr.c which
translates gnu attributes into RPC calls, and then again in the
translators's diskfs_set_translator. See for instance in
hurd/ext2fs/inode.c's
Hello,
As part of the effort of creating vm-images for the Hurd using Guix, it
would be nice to use extended file attributes to set passive
translators.
In particular, it would be helpful if we could use
setfattr --name=gnu.translator --value=/hurd/pfinet 1
That would allow us to boot
