* system: Introduce a disjoint UUID type.Ludovic Courtès2017-09-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Conceptually a UUID is just a bytevector. However, there's software out there such as GRUB that relies on the string representation of different UUID types (e.g., the string representation of DCE UUIDs differs from that of ISO-9660 UUIDs, even if they are actually bytevectors of the same length). This new <uuid> record type allows us to preserve information about the type of UUID so we can eventually convert it to a string using the right representation. * gnu/system/uuid.scm (<uuid>): New record type. (bytevector->uuid): New procedure. (uuid): Return calls to 'make-uuid'. (uuid->string): Rewrite using 'match-lambda*' to accept a single 'uuid?' argument. * gnu/bootloader/grub.scm (grub-root-search): Check for 'uuid?' instead of 'bytevector?'. * gnu/system.scm (bootable-kernel-arguments): Check whether ROOT-DEVICE is 'uuid?'. (read-boot-parameters): Use 'bytevector->uuid' when the store device is a bytevector. (read-boot-parameters-file): Check for 'uuid?' instead of 'bytevector?'. (device->sexp): New procedure. (operating-system-boot-parameters-file): Use it for 'root-device' and 'store'. (operating-system-bootcfg): Remove conditional in definition of 'root-device'. * gnu/system/file-systems.scm (file-system->spec): Check for 'uuid?' on DEVICE and take its bytevector. * gnu/system/mapped-devices.scm (open-luks-device): Likewise. * gnu/system/vm.scm (iso9660-image): Call 'uuid-bytevector' for the #:volume-uuid argument.
* mapped-devices: Cope with delayed appearance of LUKS source.Mark H Weaver2017-06-07
| | | | | | | | Fixes <https://bugs.gnu.org/27242>. * gnu/system/mapped-devices.scm (open-luks-device): If 'find-partition-by-luks-uuid' fails, try again once per second, up to ten times.
