chrootuser - run a command chrooted as given user
chrootuser
user dir command [options]
This tool executes a given command
chrooted like chroot(8)
. Unlike chroot you must specify an user account
to switch to after chrooting. Mapping of user name to user id will be done
before chroot() call.
As a special case the capabilities CAP_SYS_CHROOT and CAP_SYS_MODULE will
be removed if a user with UID 0 will be specified. To support this your
kernel must be >= 2.6.25. But don’t rely on proper removing the capabilities.
Don’t start any black or evil software with this. A chroot environment is
not a jail. You have been warned.
The return value is 1 if forking
failed otherwise 0.
chrootuser nobody /usr/chroot php -i
