    ZFS How to un-ZFS-ify a drive?

    You may want to check what util-linux wipefs does or even call it with `wipefs -a -f $DEV` because I remember dd at the beginning not being enough sometimes. =/

    ZFS How to un-ZFS-ify a drive?

    Using CoW filesystems on devices like USB pendrives and SD cards with no wear leveling is a bad idea due to the write amplification. Someone should tell the NomadBSD guys to add this warning.

    How to determine if SSD is faulty

    Install smartmontools and run `smartctl -x /dev/$disk` LLM's like ChatGPT turn out to be very good at interpreting the results.

    Wrapper around pkg(8) to automatically mount pkg cache in tmpfs and create a ZFS boot environment

    To avoid reinventing the wheel, there are the 3 workflows I know of: 1. Illumos pkg creates a new BE by default except when installing new packages. 2. openSUSE's zypper creates a Btrfs snapshot everytime, even when removing packages, keeping a configurable maximum of 10 snapshots. 3.

    Wrapper around pkg(8) to automatically mount pkg cache in tmpfs and create a ZFS boot environment

    I know modern SSD's resist a bit more but I dunno about eMMC's. It's also faster to download to RAM. I'm even tempted to symlink /var/cache/pkg to /tmp which is already tmpfs in my case but want to do it in a secure way.

    Wrapper around pkg(8) to automatically mount pkg cache in tmpfs and create a ZFS boot environment

    I'm experimenting with this wrapper around pkg(8) to automatically mount the pkg cache in tmpfs and create a ZFS boot environment. The reason for using tmpfs is to prevent a eMMC/SSD from wearing. Any suggestions for improvements are welcome. #!/bin/sh # # Wrapper around FreeBSD pkg(8) to...

    Please recommend me a good free online course to learn linux or bsd console.

    You can't go wrong with the classics. In addition to The UNIX Programming Environment recommended above I'd also add Advanced Programming in the UNIX Environment by Richard W. Stevens. Any book by this author is a collectible item. Both explain the concepts as well as the implementation...

    Reboot causes network card to fail

    On some systems I have to do a poweroff and manual power on because a reboot may leave me without network connectivity. Why is that?

    ccache and/or META_MODE for kernel dev

    I've been using META mode with success. I should probably try ccache to avoid loading the filemon kernel module.

    This seems like an elaborate prank to make fun of minimalism or someone hasn't yet realized that the real world is orders of magnitude more complex than IT.

    Rob Pike has had it with the AI tech companies/bros….

    Why is he so angry? What was his "minor role" in enabling this assault? Creating Golang & UTF-8 certainly wasn't.
