--------------------

`mock`一般初始化命令：

mock -r fedora-15-x86_64 --init

这样在`/var/lib/mock/fedora-15-x86_64` 目录下会生成 `result` 以及 `root` 目录。

但是，有时根目录空间不够，导致无法进行`mock`编译。需要手动指定`root`目录所在位置。（主要是`root`占用空间比较大）

则可以使用下面的命令，在编译时指定`root`目录到`/mnt/disk`

mock -r fedora-15-x86_64 --rootdir=/mnt/disk/

    Usage: mock [options]
    
    Options:
      --version             show program's version number and exit -h, --help show this help message and exit --rebuild rebuild the specified SRPM(s) --chain build multiple RPMs in chain loop --buildsrpm Build a SRPM from spec (--spec ...) and sources(--sources ...) or from SCM --debug-config Prints all options in config_opts --shell run the specified command interactively within the chroot. Default command: /bin/sh --chroot run the specified command noninteractively within the chroot. --clean completely remove the specified chroot --scrub=[all|chroot|cache|root-cache|c-cache|yum-cache|dnf-cache] completely remove the specified chroot or cache dir or all of the chroot and cache --init initialize the chroot, do not build anything --installdeps install build dependencies for a specified SRPM or SPEC file -i, --install install packages using package manager --update update installed packages using package manager --remove remove packages using package manager --orphanskill Kill all processes using specified buildroot. --copyin Copy file(s) into the specified chroot --copyout Copy file(s) from the specified chroot --pm-cmd Execute package management command (with yum or dnf) --yum-cmd Execute package management command with yum --dnf-cmd Execute package management command with dnf --snapshot Create a new LVM/overlayfs snapshot with given name --remove-snapshot Remove LVM/overlayfs snapshot with given name --rollback-to Rollback to given snapshot --umount Umount the buildroot if it's mounted from separate
                            device (LVM/overlayfs)
      --mount               Mount the buildroot if it's mounted from separate device (LVM/overlayfs) --localrepo=LOCALREPO local path for the local repo, defaults to making its own (--chain mode only) -c, --continue if a pkg fails to build, continue to the next one -a REPOS, --addrepo=REPOS add these repo baseurls to the chroot's yum config
      --recurse             if more than one pkg and it fails to build, try to
                            build the rest and come back to it
      --tmp_prefix=TMP_PREFIX
                            tmp dir prefix - will default to username-pid if not
                            specified
      -r CONFIG, --root=CONFIG
                            chroot config file name or path. Taken as a path if it
                            ends in .cfg, otherwise looked up in the configdir.
                            default: default
      --offline             activate 'offline' mode.
      -n, --no-clean        do not clean chroot before building
      --cleanup-after       Clean chroot after building. Use with --resultdir.
                            Only active for 'rebuild'.
      -N, --no-cleanup-after
                            Don't clean chroot after building. If automatic cleanup is enabled, use this to disable. --cache-alterations Rebuild the root cache after making alterations to the chroot (i.e. --install). Only useful when using tmpfs plugin. --nocheck pass --nocheck to rpmbuild to skip 'make check' tests --arch=ARCH Sets kernel personality(). --forcearch=FORCEARCH Force architecture to DNF (pass --forcearch to DNF). --target=RPMBUILD_ARCH passed to rpmbuild as --target -D 'MACRO EXPR', --define='MACRO EXPR' define an rpm macro (may be used more than once) --macro-file=MACROFILE Use pre-defined rpm macro file --with=option enable configure option for build (may be used more than once) --without=option disable configure option for build (may be used more than once) --resultdir=RESULTDIR path for resulting files to be put --rootdir=ROOTDIR Path for where the chroot should be built --uniqueext=UNIQUEEXT Arbitrary, unique extension to append to buildroot directory name --configdir=CONFIGDIR Change where config files are found --config-opts=CLI_CONFIG_OPTS Override configuration option. --rpmbuild_timeout=RPMBUILD_TIMEOUT Fail build if rpmbuild takes longer than 'timeout' seconds --unpriv Drop privileges before running command when using --chroot --cwd=DIR Change to the specified directory (relative to the chroot) before running command when using --chroot --spec=SPEC Specifies spec file to use to build an SRPM --sources=SOURCES Specifies sources (either a single file or a directory of files)to use to build an SRPM (used only with --buildsrpm) --symlink-dereference Follow symlinks in sources (used only with --buildsrpm) --short-circuit=SHORT_CIRCUIT Pass short-circuit option to rpmbuild to skip already complete stages.
