uEnv.txt parameters are ignored (maybe) (2 replies)

I've put the latest rootfs onto a USB and am booting a Pogoplug Mobile v4.
In the boot/uEnv.txt file I have the following:
custom_params=zswap.enabled=1 init=/bin/systemd initramfs.runsize=23M

Initially I noticed that the Pogo wasn't booting with systemd enabled. I used a workaround for this presented here: https://forum.doozan.com/read.php?2,60589,64714#msg-64714

When I run `dmesg` I see the following when looking for zSwap status (but maybe zSwap is enabled by default? because this is present without /boot/uEnv.txt in place):
zswap: loaded using pool lzo/zbud

Finally I want the tempfs to be larger so I can reload service daemons during package installations/upgrades. uEnv.txt is also not being utilized for setting this 23M value.
tmpfs          tmpfs      11M  380K   11M   4% /run

Bodhi's comment here from May 2018 mentions a typo and uEnv.txt not loading and offers a solution. I'm not sure if the same command will work if I'm already booting into systmd, or if that matters. I simply want uEnv.txt to be read from.

Thanks for any insights
