From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

This seems to be not uncommon problem with default setup of cachy. Recommendations there are that 2gb default for /boot is too small and some other tips to slim it down.

Remove old entries youve created with this tool, or grow that partition.

There's no reason you should have a ton of different boot entries to snapshots.

what tool?

There’s no reason you should have a ton of different boot entries to snapshots.

limine-snapper-info says I have 0 snapshots out of 8.

Then what's taking up all the space? If you want the tool to work, then grow the partition to get past the space limitation. Simple as that.

[–] Comexs@lemmy.zip 1 points 11 hours ago (1 children)

I don't have even the slightest idea of what is take up all the space. My main problem isn't that the snapshot feature isn't work but the fact that I don't know why its saying 85% of the boot partition has been usage up is my main concern. Just like you said I could just increase the size of the partition but that might just delay my issue until later and then I would have the same issue but twice the size.

My guess is some firmware or modules that just makes it that big and if you want room for snapshots you need to resize (or uninstall some variant if not needed). OS installer might have too small default size for a setup like this.

300MBish for a kernel is totally normal and you have 3 variants installed.

[–] dnub@piefed.social 2 points 11 hours ago

Exactly, can't you put a 5 or 10 snapshots limit where older get deleted as new ones are created? Timeshift has that

[–] ada@lemmy.blahaj.zone 1 points 10 hours ago

The quickest and easiest solution would be to update your snapper config and reduce the number of snapshots you keep.
