This installs zram-init and sets it to start on boot for all
devices/UIs. The included conf.d/zram-init also allows diabling using
zram swap or overriding the size by using a deviceinfo var.
I did an analysis of the pmos base install size with the 'none' UI
selected, after depending on zram-init, and the following new package is
installed:
zram-init-11.1-r1 installed size: 40 KiB
These packages are dependencies of zram-init, however they are already
installed in the base image (with 'none' UI) so they are not counted
above:
util-linux-misc-2.38.1-r0 installed size: 6816 KiB
e2fsprogs-extra-1.46.5-r4 installed size: 1324 KiB
So this seems like a very small price to pay for the benefit of not
making the logic/implementation more complicated than this.
* Starting busybox syslog ... [ ok ]
ssh-keygen: generating new host keys: RSA ECDSA ED25519
* Starting sshd ... [ ok ]
zram swap: activating with size: 243 MB
* Loading zram module...
[ ok ]
* Swap->zram0
[ ok ]
* Starting local ... [ ok ]
This change introduces one new deviceinfo variable:
deviceinfo_zram_swap_pct: percentage of RAM to use for zram swap
Default percentages if the second var is unset are explained in the
zram-init file this commit adds. A value of 0 disables zram swap.
