[PATCH 0/2] hurd-boot: Cleanups: Remove MAKEDEV, then use setxattr (on the Hurd). |

From: Jan Nieuwenhuizen <janneke@gnu.org>
Hi!
Several variants of these patches were present on wip-hurd-vm before.
Currently, we are running MAKEDEV from activation, and thus need hurd, bash,
coreutils and sed in PATH.
The first patch replaces that with scheme code, which seems a no-brainer to
me. Then we only need hurd in PATH for settrans and gettrans.
The second patch then switches to using setxattr instead of settrans; alas we
still need gettrans as getxattr behaves "funny" on translated nodes. I
suppose that would be a question for the bug-hurd?
Greetings,
Janneke
Jan (janneke) Nieuwenhuizen (2):
hurd-boot: Create individual translators instead of running MAKEDEV.
hurd-boot: Use 'setxattr' instead of invoking settrans.

"Good" :-)

Oops, removed this mid-way change-of-mind sublimation.

...ah, interesting. ! is for scheme'y imperativeness.

Pushed this serie master as f25e8f76fec03e5a31c221e7427d6962ece1aa67
That was all I have all from wip-hurd-vm. At least until we decide to
risk using the linux xattr patch (looks like that will be in linux-5.8).
