* grub: replace legacy grub install scriptsAlejandro Sirgo Rica2024-10-221-31/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Translate old legacy grub scripts into grub.py Implement ogGrubInstallMbr as install_main_grub() and ogGrubInstallPartition as install_linux_grub(). Add grub configuration file generator through the classes GrubConfig and MenuEntry. Ensure EFI tree structure compatibility with legacy code. The structure of the created folders in the ESP is non-standard, efi binaries are usually located in the folder below the EFI/ directory. Structure used by ogClient: EFI/ ├── grub/ │ └── Boot/ │ ├── BOOTX64.CSV │ ├── grub.cfg │ ├── mmx64.efi │ ├── shimx64.efi │ ├── BOOTX64.EFI │ ├── grubx64.efi │ └── ogloader.efi ... The function _mangle_efi_folder handles the folder structure after grub-install to comply with the location expected by ogLive. install_linux_grub() installs a grub local to each Linux install to enable chainloading, each grub is located in EFI/Part-xx-yy/ in UEFI. The local linux BIOS grub in legacy scripts is unreliable, grub-install reports a failure during the install process. install_main_grub() installs a global grub in EFI/grub/ to show a grub menu when the pxe boot fails. The global grub contains entries to every installed os. No global grub is installed for BIOS systems, a Boot partition would be required to store the grub configuration.
* utils: Add windows_register_c_drive implementationAlejandro Sirgo Rica2024-09-121-9/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add python implementation of the legacy ogWindowsRegisterPartition function. This function configures the system partition to be considered the new C drive after a Windows image restore. The drive letter configuration is stored in the SYSTEM hive of the windows registry. The node MountedDevices contains all the configuration as key-value pairs. The C drive key \DosDevices\C: contains a different value based on the partitioning type. GPT the value is DMIO:ID: followed by the 16 byte GUID of the partition. Example: DMIO:ID:\xc9\xfc\x1c\x86\x13\x11O\t\xa2\x9c{/\xf1\xdf\xe4) MBR The value is a little endian byte sequence with 2 parts. The first 4 bytes correspond to the disk id. The second part is the byte offset start of the partition in that disk. Example: \xe1\\\x9cP\x00\x00\x10j\x18\x00\x00\x00 If we format the MBR value in a more readable way we get e1 5c 9c 50 00 00 10 6a 18 00 00 00 In this case the disk ID is 509c5ce1. The partition offset is 186a100000. This patch adds the following helper functions to: - get_disk_id_bytes(): to obtain the disk identifier. - get_part_id_bytes(): to obtain a partition identifier as UUID for MBR or DMIO:ID format for GPT. - get_sector_size(): to query the sector size of a specific disk. Read /sys/class/block/{device_name}/queue/hw_sector_size to obtain the value. This is MBR specific. - get_partition_start_offset(): to query the start sector of a specific partition and disk. Use sfdisk with the -J argument to get fdisk data in json format. This is MBR specific.
* utils: replace the legacy function ogConfigureFstabAlejandro Sirgo Rica2024-08-301-9/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Implement configure_fstab() as a replacement of ogConfigureFstab. Create src/utils/fstab.py to implement the main fstab configuration functions. Define two fstab helper classes, FstabBuilder and FstabEntry. FstabEntry Represents each line in the fstab file. Has the values: device, mountpoint, fstype, options, dump_code and pass_code. FstabBuilder Contains a list of FstabEntry. Handles loading of a preexisting fstab file and the serialization of multiple FstabEntry into a file. The fstab configuration has 3 main steps: Root partition: - Update the device field with the device where the new system is installed. Swap partition: - Preserve all the swapfile entries in every case. - If the filesystem has a swap partition: update the device field in the first fstab swap entry and remove the rest swap entries pointing to a swap partition. Only one swap partition is supported. Create a new fstab entry if no preexisting swap entry exists. - If the system has no swap partition remove every swap partition entry. EFI partition: - Update the device field of the EFI fstab entry if it exists. Create a new fstab entry if no preexisting EFI entry exists. Add get_filesystem_id to disk.py to obtain the UUID. Define every device field as a UUID. That method is more robust than a plain device path as it works after disks being added or removed.
* postinstall: ignore legacy scripts non-zero return codeOpenGnSys Support Team2024-08-301-54/+47
| | | | | legacy scripts are not reliable, legacy scripts continue processing on errors, warn on errors until they are converted to native code instead.
* postinstall: remove shell=TrueAlejandro Sirgo Rica2024-08-091-4/+5
| | | | Remove the use of shell=True.

* utils: add set_windows_hostnameAlejandro Sirgo Rica2024-07-291-0/+47
| | | | | | | | | | | | | | | | | | | | | | | Add function to redefine the hostname of a Windows install. Windows hostnames can't be larger than 15 characters due to legacy heritage. Hostname modification is done by modifying 3 registry values in the ControlSetXXX entry of the SYSTEM hive. ControlSet001 is generally the entry to be edited but one must query the value of the 'Current' key in the 'Select' entry of the SYSTEM hive to retrieve the active ControlSet. The hostname has to be introduced in the following entries: path = 'ControlSetXX/Control/ComputerName/ComputerName' key = 'ComputerName' path = 'ControlSetXXX/Services/Tcpip/Parameters' key = 'HostName' key = 'NV Hostname' The value to store in those keys is of tipe SZ and has to be encoded in UCS-2 Little Endian (utf-16-le).
* utils: add postinstall.pyAlejandro Sirgo Rica2024-07-291-0/+170
Replace ConfigureOs script by native calls to: - update BCD via hivex using bcd.py and winreg.py infrastructure. - restore efi bootloader restore_windows_efi_bootloader(). Call legacy scripts for remaining postinstall procedures to replace them incrementally. Define variable CONFIGUREOS_LEGACY_ENABLED as False by default. Run legacy configureOs when CONFIGUREOS_LEGACY_ENABLED = True. This serves as a auxiliar method to keep the restoration functional in case of problems with the new configure_os logic.
