It might be tidy if pivot_root could be used (instead of a hack based on
a chroot bug), but it'd still be unportable.
It can.
Please re-read my previous msg.
I read it. Currently pivot_root can't be used to affect a single process.
No. If you unshare your mounts namespace immediately before pivot_root,
then pivot_root will only affect that single process.
Bugger. You're right, I didn't read your previous message; I thought I
had but I was wrong.
unshare(CLONE_NEWNS);
chdir(new_dir);
pivot_root(new_dir, oldroot);
After further RTFMing, and assuming "any processes or threads which
use the old root directory" means what you imply, and surely it does,
then I agree: pivot_root already does the job. Does anybody still need
to use a bug in chroot?
