+ | |||
+ | < | ||
+ | |||
+ | # defined repo | ||
+ | less / | ||
+ | |||
+ | # admin area | ||
+ | ls -R / | ||

+ | |||
+ | # this yields an error as 7.2.1511 is already deprecated | ||
+ | wwmkchroot centos-7 / | ||
+ | "This directory (and version of CentOS) is deprecated. | ||
+ | you should use /7/ and not /7.2.1511/ in your path." | ||
+ | # so we follow their advise and edit the repo destination s/ | ||
+ | vi / | ||
+ | |||
+ | # try again | ||
+ | wwmkchroot centos-7 / | ||

+ | proc root run sbin srv sys tmp usr var | ||
+ | # du -hs / | ||
+ | 490M / | ||
+ | |||
+ | </ | ||
+ | |||
