I see in official documentation this:
#d-i partman-auto/expert_recipe string \
# boot-root :: \
# 40 50 100 ext3 \
# $primary{ } $bootable{ } \
# method{ format } format{ } \
# use_filesystem{ } filesystem{ ext3 } \
# mountpoint{ /boot } \
# . \
What is this 40 50 100
? What do these numbers mean? What size will in /boot
partition ? I have not found an explanation in the documentation? C
