[lxc-users] LXD_LVM_LVSIZE envvar usage

[Fabrizio Furnari]

I wrote in /etc/init/lxd.conf:

env LXD_LVM_LVSIZE="1GiB"

cat /proc/2343/environ
UPSTART_INSTANCE=LXD_LVM_LVSIZE=1GiBUPSTART_JOB=lxdTERM=linuxPATH=/usr/local/sbin:/usr/local/bin:/usr/bin:/usr/sbin:/sbin:/bin

So the envvar seems correctly set for the process.

Also the syntax "1GiB" should be ok, considering the test scripts from
GH....
