Arch’s kernel consumes too much memory, alpine’s kernel requires much less. I’m looking for a kernel that takes up less memory. Debian seems to have a linux-image-cloud kernel for the cloud, but I haven’t seen anything like it in aur.
build your own … target the device in question
In fact, since the memory size of the VPS is only 512M, the custom kernel will make me have to cross-compile every time I update the kernel, of course, the same is true for aur.
