    Are there too many partitions needed?

    For the past few years, I setup Fedora with
    The biosboot or boot/efi partition with boot and esp flags
    the / partition
    the /boot partition
    the /var partition
    the /home partition
    the swap partition,
    With terrabyte drives, and with the ease to setup a large partition of 400gigs,
    For simple desktops, why do we need more than three partitions vis: /boot/efi, /home and /

    use one or other - biosboot and boot/efi cannot co-exist. for EFI systems use /boot/EFI only. for legacy BIOS systems use biosboot.

    setting the flags correctly for /boot/EFI is equally as important. do not flag it as biosboot, it should be flagged boot,esp

    /var is not necessary and has not ever been really since you are not running a server

    with a machine with 16GB or more RAM you don't generally need a swap at all but if you run a large number of virtual machines like bobx001 concurrently that's going to need some kind of swap (file or partition but a partition performs marginally better).

    Re: Are there too many partitions needed?

    For years, I have been setting it up with only 2 partitions (root and swap) with no issues.

    that's quite common practice across automatic partition schemes for different distributions. The polar opposite being OpenSUSE which creates partitions for pretty much every non-temporary directory off root.

    Antikythera and Solo2101,

    In my response, which adjusted,( I replaced a / with the word or) and added a comment about flags. I believe though, with biosboot, that /boot can be integral to the / partition. Solo2101 just uses / and /root. If I was using raid or not upgrading distros every 8 months, I would do likewise.

    For my SSD though, to preserve it's life my / is an xfs partition and I created a separate /var as ext4. My /home points to a folder on a common disk that is not integral to the SSD. The SSD will outlive my computer. I am now in the "waiting for a "spinner" to die, so I can replace it with an SSD. Trivially, retrieval by xfs or writing xfs is supposedly faster than doing likewise on an ext4 partition.

    /boot can be integral to / with an EFI setup too. it's more dependent on the file system or whether you use LUKS or not. If the system uses grub2 then an XFS volume can include /boot but btrfs is not supported yet.

    When ssd drives die they just die. There is no spin up and see if you can get the data back. You have to take the board to a place that can solder a bridge to a compatible controller. So back up that ssd regularly.

    Re: Are there too many partitions needed?

    I've yet to have an SSD die and I have a few. Backup is always mandatory for one's data... that is a given. I don't bother with the OS drive as if it would ever die, it just gives me the excuse to buy a new SSD (cheap now) and load the latest LTS distro .

    Sage advice. I use Timeshift for the system and rsync for /home

    System backups are valuable if an update or upgrade renders it un-bootable. Even installing some fairly innocuous looking utilities can screw up access to a GUI as one forum member (tech...) has found recently. Occasionally that happens so no matter how rare it's best to be prepared.

    Re: Are there too many partitions needed?

    I recently had an ssd die, the second one I ever bought. I had just passed on that laptop and a few weeks later it was a brick. I did have backups for user data and configs. All my backups are to spinners, and most but not all my server data is on spinners.

    Re: Are there too many partitions needed?

    I'm just thinking now that I should buy and second drive for my server and rsync the OS to it and put it in the drawer because the hardest part about having backups is that mine are compressed and hard linked with backuppc. To access those backups I have to reestablish all the server configs which takes time. If I have a clone it is just a matter of connecting and booting.

    Yes, for the sever that would be a good idea if heavily relied on. I've the samba and nfs configs stored away, so that is really all I need to get my server back with a new install. Since only my wife and I access it, I don't consider an hour or two much downtime.... If one has an extra SSD and or HDD data drive waiting in the wings that is .

    Consider using Clonzilla for an almost image copy. https://clonezilla.org/ Install it on a vm, and then use it as appropriate.
