Top Forums UNIX for Beginners Questions & Answers Why does a fakechroot exist? Post 303020011 by hicksd8 on Thursday 12th of July 2018 04:12:45 AM

Yes, I believe that is true but also consider the scenario where a Solaris Global Zone boots a non-global zone and then sets (ie, changes) that non-global zones root directory with chroot. The parent (kernel) process of that non-global is now set to a different root directory and that affects all future users logging into that zone.

Therefore my understanding was that if the root user changed the root directory of the global zone kernel (PID 1) that would affect future users that log in??

Interesting discussion this!

NAME
zcons - Zone console device driver DESCRIPTION
The zcons character driver exports the console for system zones. The driver is comprised of two "sides:" a master side with which applica- tions in the global zone communicate, and a slave side, which receives I/O from the master side. The slave side is available in the global zones. Applications must not depend on the location of /dev or /devices entries exported by zcons. Inside a zone, the zcons slave side is fronted by /dev/console and other console-related symbolic links, which are used by applications that expect to write to the system console. The zcons driver is Sun Private, and may change in future releases. FILES
/dev/zcons/<zonename>/masterconsole Global zone master side console for zone <zonename>. /dev/zcons/<zonename>/slaveconsole Global zone slave side console for zone <zonename>. /dev/zconsole Non-global zone console (slave side). ATTRIBUTES
See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Availability |SUNWcsu | +-----------------------------+-----------------------------+ | Interface Stability |Sun Private | +-----------------------------+-----------------------------+ SEE ALSO
