sudo: effective uid is not 0 - returns after fix

[mk01]

ok, now it is clear …

the problem is that btrfs-snapshot tool is mounting whole btrfs structure under /tmp to access root of filesystem hierarchy. so being mounted under /tmp/btrfs-snap with all snapshots and subvolumes, it get's chowned.

what you can do is:

Code:

mv /bin/chown /bin/chown.bck
cat <<EOF >/bin/chown
#!/bin/sh

pstree -hp > /tmp/pstree.log

EOF
chmod +x /bin/chown
reboot

then check /tmp/pstree.log

later move /bin/chown.bck /bin/chown
but you would need root privileges. or use the trick with booting via "init=/bin/bash" .

our script should be then started instead of chown binary with only one task, print process tree with PIDs and storing it into /tmp/pstree.log
