Aptivi<p><strong>Ubuntu 25.10 will use&nbsp;Dracut</strong></p><p>While Ubuntu 25.04 is still ongoing development, there has been progress in switching from initramfs-tools to Dracut. Those tools both handle initrd generation for booting into the Linux kernel in preparation for the full system boot. The Ubuntu engineers are working hard to migrate such tool to Dracut to ensure better bootstrapping by reducing hard-coded logic as much as possible.</p><p>Initially, Ubuntu 25.04 would have used Dracut as the initrd generator, but the work wasn’t complete yet, so the Ubuntu engineers have delayed the migration to after Ubuntu 25.04 gets released so that the next version of Ubuntu uses Dracut completely.</p><p>However, you have an opportunity to <a href="https://discourse.ubuntu.com/t/dracut-will-be-supported-in-ubuntu-25-04/56556/3" rel="nofollow noopener" target="_blank">try out Dracut</a> in Ubuntu 25.04 when it gets released. This is so that you can provide feedback to the Ubuntu team about your experience with the Dracut integration.</p><p>Ubuntu 25.04 will be the last version that uses initramfs-tools as the default initrd generator, with the October release of Ubuntu being the first version that uses Dracut. This is going to be exciting news for the next year’s Ubuntu LTS release that will be out in the next April.</p><p><span></span></p><p><a rel="nofollow noopener" class="hashtag u-tag u-category" href="https://officialaptivi.wordpress.com/tag/25-04/" target="_blank">#2504</a> <a rel="nofollow noopener" class="hashtag u-tag u-category" href="https://officialaptivi.wordpress.com/tag/25-10/" target="_blank">#2510</a> <a rel="nofollow noopener" class="hashtag u-tag u-category" href="https://officialaptivi.wordpress.com/tag/dracut/" target="_blank">#Dracut</a> <a rel="nofollow noopener" class="hashtag u-tag u-category" href="https://officialaptivi.wordpress.com/tag/initramfs/" target="_blank">#Initramfs</a> <a rel="nofollow noopener" class="hashtag u-tag u-category" href="https://officialaptivi.wordpress.com/tag/initramfs-tools/" target="_blank">#InitramfsTools</a> <a rel="nofollow noopener" class="hashtag u-tag u-category" href="https://officialaptivi.wordpress.com/tag/initrd/" target="_blank">#Initrd</a> <a rel="nofollow noopener" class="hashtag u-tag u-category" href="https://officialaptivi.wordpress.com/tag/news/" target="_blank">#news</a> <a rel="nofollow noopener" class="hashtag u-tag u-category" href="https://officialaptivi.wordpress.com/tag/plucky/" target="_blank">#Plucky</a> <a rel="nofollow noopener" class="hashtag u-tag u-category" href="https://officialaptivi.wordpress.com/tag/plucky-puffin/" target="_blank">#PluckyPuffin</a> <a rel="nofollow noopener" class="hashtag u-tag u-category" href="https://officialaptivi.wordpress.com/tag/puffin/" target="_blank">#Puffin</a> <a rel="nofollow noopener" class="hashtag u-tag u-category" href="https://officialaptivi.wordpress.com/tag/tech/" target="_blank">#Tech</a> <a rel="nofollow noopener" class="hashtag u-tag u-category" href="https://officialaptivi.wordpress.com/tag/technology/" target="_blank">#Technology</a> <a rel="nofollow noopener" class="hashtag u-tag u-category" href="https://officialaptivi.wordpress.com/tag/ubuntu/" target="_blank">#Ubuntu</a> <a rel="nofollow noopener" class="hashtag u-tag u-category" href="https://officialaptivi.wordpress.com/tag/ubuntu-25-04/" target="_blank">#Ubuntu2504</a> <a rel="nofollow noopener" class="hashtag u-tag u-category" href="https://officialaptivi.wordpress.com/tag/ubuntu-25-04-plucky/" target="_blank">#Ubuntu2504Plucky</a> <a rel="nofollow noopener" class="hashtag u-tag u-category" href="https://officialaptivi.wordpress.com/tag/ubuntu-25-04-plucky-puffin/" target="_blank">#Ubuntu2504PluckyPuffin</a> <a rel="nofollow noopener" class="hashtag u-tag u-category" href="https://officialaptivi.wordpress.com/tag/ubuntu-25-10/" target="_blank">#Ubuntu2510</a> <a rel="nofollow noopener" class="hashtag u-tag u-category" href="https://officialaptivi.wordpress.com/tag/update/" target="_blank">#update</a></p>

На вполне конкретных примерах вместо 390&nbsp;Мб/с наблюдается стабильные 1,7&nbsp;Гб/с.<br><br><strong>Загрузка системы на NVMe</strong><br>Обычно, людей останавливает тот момент, что BIOS (точнее EFI) древних материнских платах не позволяет загружаться с NVMe-дисков, но это не является проблемой в случае таких систем как линуксы.<br>Т.е. сама по себе система (ОС) может располагаться на nvme-диске, но загрузчик системы с #<a class="" href="https://hub.hubzilla.de/search?tag=initramfs" rel="nofollow noopener" target="_blank">initramfs</a> и образом ядра при этом на совершенно другом диске или же вообще на вынимаемом носителе. <br>Для запуска системы нужен boot-раздел весьма скромный по размерам, хватит и 200-300 мегабайт. И располагаться таковой boot-раздел может хоть на flash'ке, хоть на SD-карточке или же быть разделом на SATA-диске.<br><br><strong>Как работает загрузка ОС?</strong><br>При включении питания #<a class="" href="https://hub.hubzilla.de/search?tag=UEFI" rel="nofollow noopener" target="_blank">UEFI</a>, оно же #<a class="" href="https://hub.hubzilla.de/search?tag=EFI" rel="nofollow noopener" target="_blank">EFI</a>, читает записи в своей энергонезависимой памяти #<a class="" href="https://hub.hubzilla.de/search?tag=NVRAM" rel="nofollow noopener" target="_blank">NVRAM</a> в поисках информации о том, какие EFI System Partition (ESP) на каких носителях следует использовать в каком порядке.<br>#<a class="" href="https://hub.hubzilla.de/search?tag=ESP" rel="nofollow noopener" target="_blank">ESP</a> это обычный раздел (partition) с файловой системой FAT16 или FAT32, которую прекрасно понимает EFI-система и на ней смотрит файлы являющиеся загрузчиками сродни: #<a class="" href="https://hub.hubzilla.de/search?tag=rEFInd" rel="nofollow noopener" target="_blank">rEFInd</a>, #<a class="" href="https://hub.hubzilla.de/search?tag=GRUB" rel="nofollow noopener" target="_blank">GRUB</a> или #<a class="" href="https://hub.hubzilla.de/search?tag=systemd-boot" rel="nofollow noopener" target="_blank">systemd-boot</a><br>Так же, в качестве загрузчика может быть и специально собранный образ ядра ОС — например, т.н. <a href="https://wiki.archlinux.org/title/EFI_boot_stub" rel="nofollow noopener" target="_blank">EFI boot stub</a>.<br><br><strong>Или проще добавить поддержку #<a class="" href="https://hub.hubzilla.de/search?tag=NVMe" rel="nofollow noopener" target="_blank">NVMe</a>?</strong><br>Иногда вполне реально научить комп грузиться с NVMe. Надо взять «Intel ME Tools» и снять дамп SPI Flash чипа на материнской плате, а в снятый образ EFI-системы добавить NVMe-драйвер (через «UEFI Tool»). После чего, уже пропатченный образ записывается обратно в SPI Flash чип на материнской плате.<br><br>Доводилось такое выполнять, используя «Flash Programming Tool» (fpt.exe) из пакета «Intel ME Tools» и это не из под Windows, а из под #<a class="" href="https://hub.hubzilla.de/search?tag=FreeDOS" rel="nofollow noopener" target="_blank">FreeDOS</a>. Создавая загрузочную флешку через dd и докидывая на неё один файл «fpt.exe».<br>Не сказать чтобы удобно, но дампить и шить из под Windows требует сперва установить и саму эту ОС и нужные драйвера от материнской платы вместе с Intel ME/AMT. И выходит, что в ряде случаев проще и быстрее лишние пару раз загрузиться с флешки.<br><br>В более поздних версиях «Intel ME Tools» для более новых материнских плат (чипсетов, PCH) появился вариант «Flash Programming Tool» и для линухов. Ненаглядный «flashrom» в ряде случаев бесполезен, может снять дамп лишь с одного из чипов, коих обычно две штуки. Т.е. вместо 12&nbsp;Мб сделает дамп лишь 8&nbsp;Мб, то же FPT во время работы показывает с какого SPI-чипа сколько снято или в него записано.<br><br>#<a class="" href="https://hub.hubzilla.de/search?tag=nvme" rel="nofollow noopener" target="_blank">nvme</a> #<a class="" href="https://hub.hubzilla.de/search?tag=nvmessd" rel="nofollow noopener" target="_blank">nvmessd</a> #<a class="" href="https://hub.hubzilla.de/search?tag=linux" rel="nofollow noopener" target="_blank">linux</a> #<a class="" href="https://hub.hubzilla.de/search?tag=hardware" rel="nofollow noopener" target="_blank">hardware</a> #<a class="" href="https://hub.hubzilla.de/search?tag=intel" rel="nofollow noopener" target="_blank">intel</a> #<a class="" href="https://hub.hubzilla.de/search?tag=IntelME" rel="nofollow noopener" target="_blank">IntelME</a> #<a class="" href="https://hub.hubzilla.de/search?tag=lang_ru" rel="nofollow noopener" target="_blank">lang_ru</a> @<a href="https://3zi.ru/@Russia" rel="nofollow noopener" target="_blank">Russia</a>
