janneke pushed a commit to branch wip-hurd
in repository guix.
commit 043079af0bafab1eb380edc1cf7b2b8e1ec53e27
Author: Janneke Nieuwenhuizen <janneke@gnu.org>

DRAFT hurd: Support second boot.
XXX This works beautifully, also on my x60, as long as the filesystem is
clean. Although our fsck in libexec/runsystem doesn't work without or with
the current ftab, this may be a bad idea?
This avoids hanging upon second boot and ensures a declarative /hurd and
/dev.
* gnu/packages/patches/hurd-startup.patch: New file.
* gnu/local.mk (dist_patch_DATA): Add it.
* gnu/packages/hurd.scm (hurd): Use it.
[arguments]: In stage create-runsystem remove /dev/urandom.
