Dear Maintainer,
* debian-11.1.0-i386-netinst.iso via non-graphical installer on VM with 134M RAM + 256M swap, i.e. low memory mode:
GNOME deselected, just SSH server (and autoselected standard system utilities) tasksel'ed during install
* apt-get install lighttpd certbot
can't (re)start both services:
"Failed to reload daemon: Refusing to reload, not enough space available on /run/systemd...
a safety buffer of 16.0M is enforced."
* Can be manually overridden by e.g. doubling to
mount -t tmpfs /run -o remount,size=32M,nr_inodes=2904,mode=700,uid=1000,gid=1000 # up from size=11616k
* "Believed fixed" in https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=862013#52 but it isn't (anymore):
As "The actual minimum memory requirements are a lot less than the [256M] listed" in release documentation
ch03s04.html.en, initramfs/tmpfs has to be >=24M rather than so small it breaks /run/systemd requirements.
* cf. https://forum.doozan.com/read.php?2,34313 for another assortment of low-memory (albeit ARM) machines.
