schroot-script-config(5) schroot chroot setup script configuration


schroot uses scripts to set up and then clean up the chroot environment. These scripts may be customised using the script-config key in . This key specifies a file which the setup scripts will source when they are run. The file is a Bourne shell script, and in consequence may contain any valid shell code, in addition to simple variable assignments. This will, for example, allow behaviour to be customised according to the specific chroot type or name.

This file is deprecated, but is still used if present; it will be obsoleted and removed in a future release. All the settings in this file are now settable using configuration keys in schroot.conf, as detailed below. Existing configuration should be modified to use these keys in place of this file.


The environment is the same as for all setup scripts, described in schroot-setup(5).


The following variables may be set to configure setup script behaviour. Note that new variables may be added in future releases. Third-party extensions to schroot which add their own setup scripts may add additional variables which are not documented here; consult the extension documentation for further details.
A file containing a list of files to copy into the chroot (one file per line). The file will have the same absolute location inside the chroot. Note that this is settable using the setup.copyfiles key.
The filesystem table file to be used to mount filesystems within the chroot. The format of this file is the same as for /etc/fstab, documented in fstab(5). The only difference is that the mountpoint path fs_dir is relative to the chroot, rather than the root. Note that this is settable using the setup.fstab key. Also note that mountpoints are canonicalised on the host, which will ensure that absolute symlinks point inside the chroot, but complex paths containing multiple symlinks may be resolved incorrectly; it is advised to not use nested symlinks as mountpoints.
A file listing the system databases to copy into the chroot. The default databases are 'passwd', 'shadow', 'group', 'services', 'protocols', 'networks', and 'hosts'. 'gshadow' is not yet copied by default, due to not being supported by all but the most recent version of the GNU C library. The databases are copied using getent(1) so all database sources listed in /etc/nsswitch.conf will be used for each database. Note that this is settable using the setup.nssdatabases key.
