unshare(1) supports `--map-auto` since util-linux 2.38. From the
[util-linux 2.38 Release Notes][1]:
> unshare(8) supports new options --map-users= and --map-groups= to map block of
> group IDs; and new option --map-auto to map the first block of user IDs owned
> by the effective user from /etc/subuid
With the new package:
$ unshare --map-auto --map-root-user sh -c 'cat /proc/self/uid_map'
0 16716 1
1 1200000 65536
The five shared libraries keep their SONAMEs, and every versioned symbol
of the 2.37.3 libraries is still exported. The package now also contains
liblastlog2, lastlog2(8) and pam_lastlog2.so (SQLite is found), the
systemd units moved from /lib/systemd/system to /usr/lib/systemd/system
(/lib is a symbolic link to /usr/lib), and there are the new commands
bits, blkpr, copyfilerange, coresched, enosys, exch, fadvise, getino,
lsclocks, lsfd, pipesz, setpgid and waitpid. None of them is owned by
another installed package.
Unlike 2.37.3, the package contains tmpfiles.d(5) files, for example
/usr/lib/tmpfiles.d/lastlog2-tmpfiles.conf. So bee’s post-install hook
/usr/libexec/bee/hooks.d/systemd-tmpfiles now runs
`systemd-tmpfiles --create`, which applies all configuration files, not
only the package’s. On hosts with an automounted /home, the line
`Q /home 0755 - - -` in systemd’s /usr/lib/tmpfiles.d/home.conf then
causes a notice:
$ sudo bee update util-linux-2.42.4-0
installing /src/mariux/beeroot/packages/util-linux-2.42.4-0.x86_64.bee.tar.bz2 ..
/usr/lib/tmpfiles.d/uuidd-tmpfiles.conf:5: Failed to resolve user 'uuidd': Unknown user
/usr/lib/tmpfiles.d/uuidd-tmpfiles.conf:6: Failed to resolve user 'uuidd': Unknown user
Detected autofs mount point '/home' during canonicalization of 'home'.
Skipping /home
removing util-linux-2.37.3-0.x86_64 ..
systemd-tmpfiles does not cross the autofs mount point and skips the
entry, so nothing under /home is changed, and the update succeeds. The
installation of any package with a tmpfiles.d file shows the same notice.

Since version 2.42.4, util-linux ships a tmpfiles.d(5) and a sysusers.d(5)
file for uuidd. MarIuX has no systemd-sysusers, so the user uuidd never
exists, and every run of `systemd-tmpfiles --create`, at boot and in bee’s
post-install hook, prints:
$ sudo bee update util-linux-2.42.4-0
installing /src/mariux/beeroot/packages/util-linux-2.42.4-0.x86_64.bee.tar.bz2 ..
/usr/lib/tmpfiles.d/uuidd-tmpfiles.conf:5: Failed to resolve user 'uuidd': Unknown user
/usr/lib/tmpfiles.d/uuidd-tmpfiles.conf:6: Failed to resolve user 'uuidd': Unknown user
The daemon has never worked on MarIuX: uuidd.socket and uuidd.service are
disabled, and the units of 2.37.3 already ran it as the non-existent user
uuidd. libuuid only asks uuidd for time-based UUIDs, and without it falls
back to generating them itself, so `uuidgen -t` still works.
Configure with `--disable-uuidd`. This removes `/usr/sbin/uuidd`, its
systemd units, its bash completion, its manual page and the two files
above, and nothing else. libuuid is still built.

sudo bee update util-linux-2.42.4-0.AI disclaimer: Drafted and assisted by claude-opus-5.5 (Claude Code).
The motivation is
unshare --map-auto(since 2.38), which maps the first block of the user’s subordinate IDs from/etc/subuidand/etc/subgid:findmntandlsblkwork with the new libraries.bits,blkpr,copyfilerange,coresched,enosys,exch,fadvise,getino,lsclocks,lsfd,pipesz,setpgidandwaitpid, as well as liblastlog2,lastlog2andpam_lastlog2.so(upstream default, as SQLite is found; nothing enables the PAM module). None of these files is owned by another installed package./lib/systemd/systemto/usr/lib/systemd/system, which is the same directory, as/liblinks to/usr/lib.uuidd, which never exists on MarIuX (nosystemd-sysusers), so everysystemd-tmpfiles --createwarnedFailed to resolve user 'uuidd', as seen when installing 2.42.4-0 on geniux. The daemon has never been able to run here (units disabled, 2.37.3 units already usedUser=uuidd). libuuid falls back to generating time-based UUIDs itself;uuidgen -tstill works.Release notes
