You don’t have to. Instead, you can try this: unshare -U echo $$ Then, in another terminal: echo -n "10000 $UID 1" > /proc/PID/uid_map echo deny > /proc/PID/setgroups echo -n "10000 GID 1" > /proc/PID/gid_map (Replace “PID” with the PID of the shell in the first terminal, and GID with your GID.) Go back to the first terminal; the ‘id’ command should show you 10000 as your UID/GID, and possibly supplementary groups as the overflow GID. >From there, you can configure and build Gnulib. Ludo’.
