+**** =/boot= free space ([[https://www.debian.org/releases/trixie/release-notes/issues.en.html#ensure-boot-has-enough-free-space][ref]])
+No worries, got the boring mono-partition setup?
+**** TODO =/tmp= switch to tmpfs ([[https://www.debian.org/releases/trixie/release-notes/issues.en.html#the-temporary-files-directory-tmp-is-now-stored-in-a-tmpfs][ref]])
+IIUC, after the first restart, should

+2. [ ] ~mount --bind / /mnt~
+3. [ ] ~rm -rf /mnt/tmp/~
+4. [ ] ~umount /mnt~
+5. [ ] restart
+6. [ ] confirm absence of syslog warnings?

+After installation, check:
+1. [ ] =linux-sysctl-defaults= installed?
+2. [ ] =net.ipv4.ping_group_range= sane?
+3. [ ] ~ping perdu.com~ works?
+**** TODO dpkg warnings about non-empty directories ([[https://www.debian.org/releases/trixie/release-notes/issues.en.html#dpkg-warning-unable-to-delete-old-directory][ref]])
+Double-check presence and content?
