Installs WayangOS onto an internal disk (UEFI, Secure Boot off). Copy this .iso to a Ventoy USB or dd it to a stick, boot the target PC, then pick the internal disk.
Storage health for servers and PCs: native SMART for SAS, SATA and NVMe (Dell PERC / MegaRAID included), remaining-life estimates, health gate and alerts, fake-drive and real-capacity checks, deleted-file recovery advice. Runs on any Linux or macOS — no WayangOS needed, no dependencies.
# install (checksum-verified, to /usr/local/bin)
curl -fsSL https://wayang.dalang.io/dcheck/install.sh | sh
# optional: also install smartmontools (apt/dnf/yum/zypper/apk/pacman/brew)
curl -fsSL https://wayang.dalang.io/dcheck/install.sh | sh -s -- --with-smartmontools
# preview without changing anything
curl -fsSL https://wayang.dalang.io/dcheck/install.sh | sh -s -- --with-smartmontools --dry-run
# run, and keep it up to date
sudo dcheck
sudo dcheck update
# fake drive? prove the real capacity (writes test files to free space)
sudo dcheck verify /dev/sdX --size 8G
# deleted a file? chance + what to do (read-only)
sudo dcheck recover /dev/sdX
sudo dcheck undelete /dev/sdX1 --to /mnt/usb/rescueRequirements: none at runtime (static binary). SMART needs root. Offline servers: download the tarball for your platform from the dcheck page.

View Install Guide →Patch and upgrade an installed box without reinstalling. WayangOS keeps two boot slots (A/B): the new image is written to the idle slot, verified, then booted. If it fails to start, GRUB falls back to the last good slot automatically, and you can roll back at any time.
# minor / patch within the installed major
sudo wayang update
# cross-major upgrade (explicit)
sudo wayang upgrade
# check only — change nothing
sudo wayang update --check
# offline bundle from USB (no internet)
sudo wayang update --from /run/media/usb/wayang-1.4.1-x86_64.wup
# go back to the previous slot
sudo wayang update --rollbackUpdates are signature-verified and only reboot when you ask (add --reboot). /data is never touched.
