Hmm, I can't say I'm happy to enlarge the base package installed
everywhere... but 380k is not that much.

I think we should instead, (possibly at build time), parse
/usr/share/base-passwd/{group,passwd}.master, and insert a new file
debian-static.conf. This should make it relatively easy to follow
changes from the distro:

cat /usr/share/base-passwd/passwd.master | \
  awk 'BEGIN { FS=":" } ; { print "u " $1 " " $3 " \"" $5 "\" " $6 " " $7 }'
# mutatis mutandis for group
cat /usr/share/base-passwd/passwd.master | \
  awk 'BEGIN { FS=":" } ; { print "m " $1 " " $4  }'
# Although I'm not sure sysusers accepts numeric groups here...

Keeping the list in sync will otherwise be a pain.
