2020-10-08hurd-boot: Create /servers/crash....* gnu/build/hurd-boot.scm (set-hurd-device-translators): Create /servers/crash. Ludovic Courtès
2020-06-27hurd-boot: Mount /proc, add /etc/mtab....* gnu/build/hurd-boot.scm (set-hurd-device-translators): Mount /proc. Add symlink to /etc/mtab into /proc/mounts. Jan (janneke) Nieuwenhuizen
2020-06-27hurd-boot: Remove duplicate calls to 'scope'....* gnu/build/hurd-boot.scm (set-hurd-device-translators): Remove duplicate calls to 'scope'. Jan (janneke) Nieuwenhuizen
2020-06-19hurd-boot: Use 'setxattr' instead of invoking settrans....Note: Using `getxattr' on the Hurd instead of running showtrans does not work (yet?). * gnu/build/hurd-boot.scm (setup-translator): Use 'setxattr' instead of invoking settrans. * gnu/system.scm (hurd-multiboot-modules): Add --x-xattr-translator-records to enable xattr-embedding of translators. Jan (janneke) Nieuwenhuizen
2020-06-19hurd-boot: Create individual translators instead of running MAKEDEV....* gnu/build/hurd-boot.scm (make-hurd-device-nodes): Do not create dev/{null,zero,full,random,urandom} mount points. (passive-translator-xattr?, passive-translator-installed?, translated?, set-translator, set-hurd-device-translators): New procedures. (false-if-EEXIST): New macro. (boot-hurd-system): Use them instead of running MAKEDEV. Jan (janneke) Nieuwenhuizen
2020-06-08gnu: services: Add %hurd-startup-service....This decouples startup of the Hurd from the "hurd" package, moving the RC script into SYSTEM. * gnu/packages/hurd.scm (hurd)[inputs]: Remove hurd-rc-script. [arguments]: Do not substitute it. Update "runsystem.sh" to parse kernel arguments and exec into --system=SYSTEM/rc. (hurd-rc-script): Move to... * gnu/services.scm (%hurd-rc-file): ...this new variable. (hurd-rc-entry): New procedure. (%hurd-startup-service): Use it in new variable. * gnu/system.scm (hurd-default-essential-services): Use it. Jan (janneke) Nieuwenhuizen
2020-06-08hurd-boot: Further cleanup of "rc"....* gnu/packages/hurd.scm (hurd-rc-script): Move implementation to ... * gnu/build/hurd-boot.scm (boot-hurd-system): ...here, new file. * gnu/build/linux-boot.scm (make-hurd-device-nodes): Move there likewise. * gnu/local.mk (GNU_SYSTEM_MODULES): Add it.
