Ludovic Courtès 2022-11-28hurd-boot: Explain why 'getxattr' cannot be used on GNU/Hurd....This is a followup to f25e8f76fec03e5a31c221e7427d6962ece1aa67. * gnu/build/hurd-boot.scm (translated?): Clarify why 'getxattr' cannot be used on GNU/Hurd. Ludovic Courtès 2022-11-28hurd-boot: Create more PTY nodes....* gnu/build/hurd-boot.scm (set-hurd-device-translators): Create more /dev/ptyp* and /dev/ttyp* nodes. Ludovic Courtès 2022-03-01initrd: Use non-hyphenated kernel command-line parameter names....This is to make it less surprising, given the common convention sets forth by the kernel Linux command-line parameters. * gnu/build/linux-boot.scm (boot-system): Rename '--load', '--repl', '--root' and '--system' to 'gnu.load', 'gnu.repl', 'root' and 'gnu.system', respectively. Adjust doc. (find-long-option): Adjust doc. * gnu/installer/parted.scm (installer-root-partition-path): Adjust accordingly. * gnu/system.scm (bootable-kernel-arguments): Add a VERSION argument and update doc. Use VERSION to conditionally return old style vs new style initrd arguments. (%boot-parameters-version): Increment to 1. (operating-system-boot-parameters): Adjust doc. (operating-system-boot-parameters-file): Likewise. * gnu/system/linux-initrd.scm (raw-initrd, base-initrd): Likewise. * doc/guix.texi: Adjust doc. * gnu/build/activation.scm (boot-time-system): Adjust accordingly. * gnu/build/hurd-boot.scm (boot-hurd-system): Likewise. * gnu/packages/commencement.scm (%final-inputs-riscv64): Adjust comment. Maxim Cournoyer 2021-12-12services: static-networking: Change interface to mimic netlink....* gnu/services/base.scm (<static-networking>)[interface, ip, netmask] [gateway]: Remove. [addresses, links, routes]: New fields. [requirement]: Default to '(udev). (<network-address>, <network-link>, <network-route>): New record types. (ensure-no-separate-netmask, %ensure-no-separate-netmask): Remove. (ipv6-address?, cidr->netmask, ip+netmask->cidr) (network-set-up/hurd, network-tear-down/hurd) (network-set-up/linux, network-tear-down/linux) (static-networking->hurd-pfinet-options): New procedures. (static-networking-shepherd-service): New procedure. (static-networking-shepherd-services): Rewrite in terms of the above. (static-networking-service): Deprecate. Adjust to new 'static-networking' API. (%base-services): Likewise. * gnu/system/install.scm (%installation-services): Likewise. * gnu/system/hurd.scm (%base-services/hurd): Likewise, and separate 'loopback' from 'networking'. * gnu/build/hurd-boot.scm (set-hurd-device-translators): Remove "servers/socket/2". * gnu/tests/networking.scm (run-openvswitch-test)["networking has started on ovs0"]: Check for 'networking instead of 'networking-ovs0, which is no longer provided. * doc/guix.texi (Networking Setup): Document the new interface. Remove documentation of 'static-networking-service'. (Virtualization Services): Change Ganeti example to use the new interface. Ludovic Courtès 2021-10-18hurd-boot: Set pfinet on the right node for AF_INET6....* gnu/build/hurd-boot.scm (set-hurd-device-translators): Fix /servers file name for AF_INET6. Ludovic Courtès
