Swapfile?? about astos HOT 4 CLOSED

You should be able to chroot into the snapshot, then follow the steps outlined by the Arch wiki (https://wiki.archlinux.org/title/Btrfs#Swap_file).

Personally I recommend using ZRAM instead (https://wiki.archlinux.org/title/Zram).

That didn't work, I tried that.... Only the fstab change persisted. Systemd gives me error now when I try to boot my system up.

Also I started to get an error from then on saying that snapshot is locked. After unlocking it and rebooting, it got fixed...

I have just 4GB of RAM so ZRAM is pretty useless for me.....

I think creating a new subvolume causes an issue... Perhaps instead of creating a new subvolume for swap, I create a swapfile in /etc or /var with btrfs filesystem mkswapfile --size 4g --uuid clear /var/swapfile and then mount that swap file.....

Would that work????

I have been able to create a swapfile based on the ArchWiki information with a few extra steps.

First mount the system partition like so (do everything as root):

mount /dev/*** /mnt -o subvolid=0

Then you can make the subvolume

btrfs sub create /mnt/\@swap

Then finally create the swapfile

btrfs fi mkswapfile --size 4g --uuid clear /mnt/\@swap/swapfile

At this point you can chroot inside the snapshot, we'll continue from there.

ast chroot <snapshot>

Make the swap path

mkdir /swap

There open up /etc/fstab and add 2 new entries.

UUID="xxx" /swap btrfs subvol=@swap,noatime 0 0 # Here use system partition UUID
/swap/swapfile none swap defaults 0 0

Now you can exit the chroot

exit 0

and deploy.

ast deploy <snapshot>

I think this process could be automated in some way or a part of the installer, or at least it deserves a section in the docs - I'll look at that later.

Hmm, I figured out a solution to swapfile just a while ago but did it a little differently...

I created a btrfs subvolume using
btrfs subvolume create /var/swap

and then created a swapfile using
btrfs filesystem mkswapfile --size 4g --uuid clear /var/swap/swapfile

and swapon /var/swap/swapfile

also updated fstab from within chroot and exited and deployed the snapshot...
I could make a PR to update the README.md too...

But I am having a lot of other issues like stuff don't make sense to me...
Is ast sync <tree> supposed to update all the packages installed from repos and aur in all the branches, since it wasn't quite doing that for me, if so then what is tree-upgrade for?? Also why was it giving file already exists error for me when I tried to upgrade... also when I upgrade do I need to upgrade for each and every child snapshot, like rebuilding hyprland-git 3 times for 3 children nodes or fetching the same package multiple times?? Also kernel updates were working when I tried to sync... I have a lot of questions about this project and maybe the README can be improved with all the necessary info and better description if you clarify my confusions...
